2.80 includes many improvements to the JIT. Instructions that touch PC are improved in performance, Page Zero is now redirected instead of emulated, allowing code within Page Zero. IRQ, FIQ and Undefined Instruction hardware vectors are now handled as instructions instead of being emulated.
Many game bugfixes added for Null dereference bugs, Page Zero access bugs and other general bugs that the authors didn't detect. Where possible these bugfixes have been implemented to work on games running under RISC OS 3.1x.
The JFD floppy imager no longer requires SparkFS, using ZLib instead and requires 900Kb less memory to image DD floppies.
A-series requirements:
- 4MB RAM minimum
- RISC OS 3.10 or newer
- ADFFS must be installed to a hard-drive
- 32MB RAM minimum
- RISC OS 3.x, 4.x or 5.23 Jun 9th 2016 or newer. Note that some games will not work on RISC OS 4.x due to the way it allocates screen memory in 1MB blocks. RISC OS 6 is not officially supported
- RISC OS 5.27 Nov 16th 2018 or newer (download link)
- To get legacy TV MODEs working (0 to 15), you can try this Monitor file for 75Hz EGA on VGA
EGAonVGAMonitor.zip
- Any revision Pi, from Pi 1 to Pi 4, including Pi Zero
- RISC OS 5.27 Nov 16th 2018 or newer (download link)
- Ensure fake_vsync_isr=1 is uncommented in !Boot.Loader.CONFIG/TXT
- You must disable GPU mode change support using the applicable method below. Note that if you have multiple entries in CMDLINE/TXT, they should be separated with spaces and not new lines.
Non-NOOBS RISC OS:- Hold SHIFT and browse to !Boot.Loader from the root of the drive
- Create CMDLINE/TXT with the following contents:
Code: Select all
disable_mode_changes
- Hold SHIFT at power on to enter the NOOBS configuration
- Select Edit Config
- Add the following to CMDLINE.TXT:
Code: Select all
disable_mode_changes
- (optional) For a blocky pixel retro gaming look, turn off the default GPU filtered upscaling by editing !Boot.Loader.CONFIG/TXT and add the following lines:
Code: Select all
#set GPU upscaling to nearest neighbour scaling_kernel=8 - (optional) If your display supports 50Hz, you can force the Pi to use 50Hz by editing !Boot.Loader.CONFIG/TXT and adding the following lines. Uncomment one of the hdmi_mode values:
At other monitor frequencies, games will still run at the correct rate but micro stutter may be noticeable where extra frames are added to make up the differenceCode: Select all
hdmi_ignore_edid=0xa5000080 # hdmi_group=1 #576p @ 50Hz #hdmi_mode=17 # #720p @ 50Hz #hdmi_mode=19 # #1080p @ 50Hz hdmi_mode=31
Known issues
- Does not support the protection used by Chequered Flag (RO2 version) when running on RISC OS 3.1x (talks directly to the FDC via IOC)
- Shelling out of the desktop (Ctrl-Shift-F12 twice) hangs under RedSquirrel if an HD floppy is mounted on RO3.5+ ARM710
- Although Caverns runs fine under VIDC translation on the A7000, on a RiscPC the scrolling isn't quite correct
- OMAP based cores are untested and may not work
- Some games that use overscan may result in a blank screen on a RiscPC
- 26bit WIMP app support under RISC OS 5 can randomly lock the machine (related to a feature of RISC OS, which doesn't preserve memory page access across task switches)
- Hardware scrolling is still in effect when returning from an emulated legacy mode, to the desktop under RISC OS 5
- When switching between an emulated mode and the desktop, logical memory space is leaked eventually resulting in logical memory exhaustion. Refer to the ROOL discussion for further details
- Cache flushing is not performed at VSync on StrongARM based RiscPC, resulting in flickering
- JIT will not work under RPCEmu as it does not generate Page Faults when User mode writes to pages with Supervisor only write permissions
- Games that alter the Wimp Mode might cause a lock when exiting back to the Wimp under RISC OS 5:
- Cyborg
- Dreadnoughts
- Guile
- Put It!
- Wizard Apprentice
- WIMP based titles may lock the machine:
- Abuse
- Alderbaran
- Black Angel
- Demon's Lair
- E-Type II
- Elite
- Emotions - Search for Humanity
- EuroBlaster (from Flying High)
- Fervour
- Foray
- Frak!
- Global Effect
- Hamsters
- Haunted House
- High Risc Racing
- Ixion
- Joust (from Flying High)
- Karma - The Flight Trainer
- K.V.
- Mah-Jong Patience
- Merp (from Mirror Image and Merp)
- Premier Manager
- Scrabble
- Shuggy
- SimCity
- TANKS
- The Chaos Engine
- Virtual Golf
- WaveLength
- Formula Fun - doesn't hide the text cursor and doesn't wait on the track map screen
- Frak! - music is glitchy and the game has a screensaver, which you can't get out of without hitting ESC
- James Pond 2: Robocod (non-SA) - music key is wrong. Also happens on physical
- Abuse - Aborts when starting a new game
- Brutal Horse Power - Audio is crackly
- TEK 1608 - FileCore in use error if terminated via CTRL-SHIFT-F12

Changes since 2.74:
- JIT codelets that reference PC no longer check the address they're jumping too, reducing the codelet size:
- MOV PC, Rn ... codelet reduced from 13 to 7 instructions
- MOVS PC, Rn ... codelet reduced from 16 to 15 instructions
- <alu> PC, Rn ... codelet reduced from 13 to 7 instructions
- <alu> PC, PC ... codelet reduced from 13 to 8 instructions
- <alu>S PC, Rn ... codelet reduced from 24 to 15 instructions
- <alu>S PC, PC ... codelet reduced from 24 to 23 instructions
- LDM Rn, {..., PC} codelet reduced from 14 max to 9 max instructions
- LDM Rn, {..., PC}^ codelet reduced from 20 max to 19 max instructions
- LDR PC, [PC, ... codelet reduced from 13 to 8 instructions
- LDR PC, [Rn, ... codelet reduced from 12 to 7 instructions
- JIT IRQ handler now uses more registers to allow STM/LDM when ensuring codelets are atomic
- JIT with instruction tracing enabled allocate_codelet was trying to reuse codelets, regardless of the value of JIT_codelet_reuse. This was causing ADR codelets to be reused, which return to the wrong address
- JIT IRQ handler on IOMD wasn't loading IOC IRQA status after calling an IRQv claimant, if the claimant corrupts R12
- JIT IRQ handler terminate_current_task was marking the task as killed even when the current task wasn't the one being killed or IRQsema was set
- JIT now sets the environment variable ADFFS$JIT when the JIT is running to allow Obey files to avoid running further 26bit code if the JIT is shutdown mid-script
- JIT release_all_ChangeEnvironmentV wasn't releasing UpCall correctly, now also releases Unused SWI handler if claimed (fixes Cobalt Seed when terminated via CTRL-SHIFT-F12)
- JIT <alu>S PC, PC wasn't clearing Rn (fixes Pacmania)
- JIT ChangeEnvironmentV_handler now checks for environment handlers being pointed at hypervised handlers and corrects the address (fixes CTRL-SHIFT-F12 in Populous)
- JIT _needs_pre_veneer now corrects the hypervised previous environment handler codelet address (fixes CTRL-SHIFT-F12 in Populous)
- JIT centralised code that sets codelet_cache_flush into allocate_codelet
- JIT hv_OS_CallASWI_codelet_required rewritten to call static code in application space, instead of allocating a new codelet (fixes random crashes when starting Populous)
- JFD imager memory requirement reduced from 1920K to 1056K for DD and 1856K for HD
- JFD imager no longer dependent on SparkFS and now extracts the Boot script before attempting to image the floppy
- JIT now uses Wimp_Extend to determine the initial Appspace memory allocation instead of Wimp_SlotSize, to better support Pi4
- Data Abort handler now checks Early Abort Mode via OS_PlatformFeatures on RO5 if not running on IOMD
- Data Abort handler now unmaps IOC chipset memory areas if the Wimp isn't running and will correctly check for Early Abort mode on IOMD unmapping &2000000 in the process
- Now checks for an Abort32 stack on 26bit IOMD and will locate in a DA if its not set, fixes JIT on 26bit StrongARM
- JIT codelet optimizations:
- MOV{S} Rd, PC codelet reduced from 12 to 9/7 instructions on 32/26 bit
- EOR/SUB/ADD/ORR/BIC Rd, PC, #0 codelet reduced from 3 to 2 instructions
- JIT removed temporary stack in allocate_codelet on 26bit IOMD
- JIT IRQ vector is now a branch to a codelet
- IOC_trigger_device_9 and IOC_timers were not checking if a JIT task was active before calling the IRQ vector, which could cause a crash when ADFFS initially installs its GraphicsV driver
- JIT Page Zero is now redirected to a dedicated block to allow code in Page Zero
- JIT moved all dedicated Page Zero variables into the emulated Page Zero
- JIT UND32 stack set to a DA on IOMD, if it's not been set by the OS
- JIT Abort handler semaphone wasn't cleared when reporting an abort, which would cause any JIT aborts generated during JIT shutdown to generate an OS Abort and the shutdown to fail
- JIT kill_26bit_modules no longer get stuck in a loop if a 26bit Module fails to shutdown cleanly
- JIT Claim_DataAbort_Vector wasn't clearing the Abort handler semaphone which could cause the JIT to fail when launching a game after terminating a previous game with CTRL-SHIFT-F12
- Abort handler wasn't checking if an unaligned memory access was within JIT Appspace or DA2 before passing to the JIT
- JIT OS scratch space (4000-8000) is no longer remapped and left for the OS to provide
- JIT Event handlers are now called unelevated
- JIT Free_Transient_Stack was setting the CPU mode instead of disabling IRQ/FIQ
- JIT call_vector_claim now uses transient stacks and has been recoded to handle re-entrancy when calling code in USR mode
- R9 is now pointed to the channel SCCB when calling Voice Generator Instantiate or Free entry points (fixes Page Zero access errors in Command Ship and probably others)
- RISC OS 2 VIDC MODE table added (fixes Enter The Realm)
- Removed the check for Sound_Config being claimed in IOC_trigger_device_9, as it prevented the IRQv vector being called in Zelanites when SSBC was triggered
- OS_ClaimDeviceVector now clears the taskID associated with a claimant if it wasn't claimed under the JIT
- JIT IRQ1V moved into task Page Zero and now defaults to point to a JIT exit instruction
- JIT *GO is now detected by checking explicitly for "GO[32][00]" as the commandline
- JIT *GO environment is now passed on if set (ie *GO 8000;!RunImage value)
- GraphicsV 5 was not using the existing Pointer height if the shape wasn't being updated
- JIT moved Environment handler free code out of the handler codelet and into ADFFS, to avoid IRQ potentially reallocating the memory and causing a hard lock
- JIT Undefined hardware vector implemented (used by K.V. to determine ARM2 status)
- JIT MRC CP15,0,Rx,C2,C0 now triggers the undefined instruction vector if emulating <RO3.10
- JIT entry now checks for areas in Page Zero that cannot contain code
- JIT hv_reset_memory_block wasn't checking if the start address was in Page Zero, which would cause a lock when BBC6502Emulator loads BBC code (fixes Enthar Seven)
- JIT an Abort during a Module Finalise no longer locks the machine
- JIT OS_Module, 18 now reports "ARM3Support" or "ARM" exists when emulating RO2.01-3.49 and RO3.50-4.99 respectively
- JIT OS_ReadMemMapInfo now returns the max RAM the JIT supports
- JIT MRC CP15,0,Rx,C0,C? now returns StrongARM when under the ARMv4 JIT
- JIT OS_Module, OS_GBPB were not generating an error if X wasn't set
- SWI handler wasn't triggering an error for SWI that were not passed to the OS, if X wasn't set
- JIT OS_CallASWIR12 wasn't clearing the X bit before checking the SWI #
- JIT CallBack handler wasn't correcting PC on IOMD 26bit (fixes Interdictor)
- JIT CLibCounter, RISCOSLibWord, CLibWord weren't being reset during initialisation (bug introduced in 2.80y)
- JIT hardware vectors are now set as LDR or B instructions to match the emulated OS version
- JIT moved all 26->32bit exit points to the top of the JIT translated RMA space (fixes Lemmings 2, Gribbly's Day Out and meets Lotus Turbo Challenge 2's requirement for the IRQ vector branch to be above DF54)
- JIT kill_26bit_modules now directly calls Module finalise entries and the hypervised SWI exit handler will pass any errors that would ordinarily be reported back to kill_26bit_modules, to ensure errors do not interrupt Module termination
- JIT RMKill wasn't reporting an error if the Module lookup failed
- JIT RMKill was freeing the 26bit Module address space even if Finalise failed
- JIT Sound_RemoveVoice and OS_Release were not reporting errors correctly
- JIT call_module_entry rewritten to use stacks for variables
- BASICTrans updated to resolve a bug in its Finalise
- ExSound updated to 4.03 - checks for Null derefences to fix some of The Fourth Dimension titles
- JIT 26bit Module loader wasn't correctly checking for 32bit Modules when emulating <RO 3.60
- JIT kill_26bit_modules may have missed 26bit Modules if Service_Sound was issued while it was checking the Module chain
- JIT minor optimisations to the hypervised SWI dispatcher
- JIT SWI exit errors are now trapped during Module finalise and will now also generate an error if X isn't set for the following SWI:
OS_AddCallBack, OS_AddToVector, OS_CallAfter, OS_CallEvery, OS_Claim, OS_FSControl, OS_GetEnv, OS_GBPB, OS_Heap, OS_HeapSort, OS_Memory, OS_Module, OS_PlatformFeatures, OS_ReadSysInfo, OS_ServiceCall, OS_Release, OS_RemoveCallBack, OS_RemoveTickerEvent, OS_ScreenMode, Sound_InstallVoice, Sound_LinearHandler, Sound_Mode, Sound_QSchedule, Sound_RemoveVoice, Squash_Decompress, Wimp_SlotSize - JIT wasn't claiming Environment handlers when the Wimp wasn't active
- JIT CallBack handler wasn't using the PSR from regdump PC for the corrected return address on 26bit IOMD
- ADFGO was not calling FSControl_StartApplication with a valid command tail or CAO
- pre_SWI_veneer wasn't clearing V from SPSR before passing to the OS SWI handler
- JIT OS_RemoveCallBack was marking the CallBack as removed even if it failed to be removed
- BASIC26 is now marked at 26bit in its header
- JIT added additional checks to the SWI chunk in 26bit Modules
- JIT wasn't bypassing the 26bit Module checks when loading BASICtrans
- JIT Insert Module into RMA wasn't resetting the memory block the Module was copied too
- JIT 26bit Module handler wasn't restoring the SWI veneer address before exiting, which could cause CPSR to become corrupt
- no longer clears flags in R14 on entry to the SWI or IRQ handler
- UnSqzAIF wasn't correctly checking for a valid Squeeze signature and was also checking all files, not just Absolute (bug introduced in 2.73e)
- ADFScreenLoad wasn't reporting an error if the file was not found
- Switched ADFScreenLoad to use OS_File 17 instead of 23, so it works with the protection used in Saloon Cars
- OS_SpriteOP 3 was corrupting R0 if an error occurred
- JIT vector calls were not preserving exit flags
- JIT wasn't restoring the Page Zero Compatibilty page when shutting down
- JIT Wimp_Initialise now points R2 to a valid string if its unset (fixes Emotions - Search for Humanity)
- reset_audio now notifies kill_26bit_modules when its about to RMReInit SoundDMA, to prevent issues while its trawling the Module list
- QTM updated to v1.45d
- load_26bit_module no longer checks the OS flags in the SWI chunk (fixes Rick Dangerous TrkDriver) (bug introduced in 2.80rc2)
- Service_ModeChange was incorrectly triggering a GraphicsV 2 for all mode changes, not just Service_ModeExtension mode changes
- blit_update_VIDC now ignores resolution changes unless HCR or VCR have changed, or the display start/end have encroached into the boarders (fixes Stunt Racer 2000 intro)

https://www.jaspp.org.uk/packages/releaseNOTE: You must use "Boot floppy" to run supported games. If you don't, you could end up with a machine that isn't bootable, as some games alter the CMOS. Provided "Boot floppy" is used, ADFFS will prevent games from altering both the CMOS and unplugging modules.
DO NOT try to run a game by launching it's Icon - it will almost certainly damage your machine.
