@Jon
Doing some tests! Will report anything I find with this new RC.
ADFFS 2.80 public beta
Re: ADFFS 2.80 public beta
Assuming no feedback is good feedback, I'll aim to make the final build available over the weekend.
Re: ADFFS 2.80 public beta
@Jon: Saw nothing strange to report in all the games I tested. Had a good play at some of them without anything to report.
Which, as you say, is a very good thing!

Re: ADFFS 2.80 public beta
Thanks, I've just made the final release available via the usual channels. The only difference between it and RC3 is Null dereference checking is turned off - just in case we missed any game bugs during testing.
Re: ADFFS 2.80 public beta
Issues noted with SWIV:
Work-in-progress !Run replacement script:
NOTE: This won't currently work on StrongARM as ADFFS 2.80 falls foul of a CPU errata
- F1 is not pausing the game and needs holding to do anything (fixed by moving the EventV game code call into the main game loop)
- the screen update code sits under in IRQ event (EventV originally, Device 3 under the JIT). Pressing F1 puts the code into a loop at 1415C. Ignoring the fact that IRQ code should never loop like this, the IRQ handler doesn't check for re-entrancy and subsequently fills the stack and crashes
- the game essentially needs rewriting to run under USER or a CallBack that handles re-entrancy
- Speed issue on physical RiscPC (fixed by adding OS_Byte 19 to main game loop)
- possibly related to the EventV code being moved to Device 3 to avoid the game causing C based Modules to crash
- Disc protection check can fail if the game is installed to an ADFS attached HD (fixed vicariously by decrypting Loader for game patching)
- bug in Loader which only performs the protection check if ADFS is the Temporary Filing System
- The disk may need reimaging as the check fails when ADFS is forced as the TFS (disk image is good, must be another protection check failing)
- behaviour of OS_Args 0,0 changed from RISC OS 3 which needs adding to ADFFS
- 1C1B0 Aborts writing to the screen when exited on a physical RiscPC (fixed vicariously)
- At the point the Abort occurs, the game's EventV code hasn't been removed and the game hasn't issued OS_Exit, so possibly an Abort being reported and it's not reset the machine fully?
- Joystick mis-detection on RiscPC (fixed by correcting code)
- bug in the code that checks for RTFM. It's calling Joy_Read0 when it should be calling Joy_Test
- Joysticks are being detected with USBJoystick loaded (can't currently be fixed)
- USBJoystick emulates VTJoystick_Status, Joy_Test and Joystick_Read and there's no SWI to actually detect if a Joystick is attached, so this can't currently be fixed
- Crashes on the high-score page under RISC OS 3.x (fixed vicariously)
- this appears to be related to the hardware IRQ vector code that performs the palette swap mid-frame on that screen. I suspect it's corrupting the stack or not handling re-entrancy
- T1 based palette swap code doesn't account for the pixel clock rate (fixed)
- Palette swap Y location drifts on a RiscPC. Corrected T1 values for EGAonVGA, which ADFFS uses for MODE 9
- Palette swap Y offset is slightly out on the highscore page on a GPU. Initial T1 offset adjusted to fix
- StrongARM issues
- Crashes when launched if the ADFFS400 Module isn't loaded directly before running the game. Almost certainly CPU cache or IRQ related (to be investigated)
- Crashes when exited if a key is pressed (fixed)
- Screen caching causing flickering (fixed by turning off screen caching)
- ARM6/7 macrocell issues
- hardlocks when the Event 4 code is called to set the default palette (fixed in ADFFS 2.81)
- IRQv T1 palette swap code is not working (fixed by running code natively)
- Title loop runs slightly too fast (fixed by implementing a PLL)
Work-in-progress !Run replacement script:
NOTE: This won't currently work on StrongARM as ADFFS 2.80 falls foul of a CPU errata
- Updated 18/07/22 to add frame pacing into main game loop, instead of relying on ADFFS
- Updated 23/07/22:
- implemented a PLL to update the screen and elements so they match the original on an 8MHz ARM2
- corrected the music fade-out pause when starting a game
- game now runs natively on ARM610/710
- T1 palette swap values corrected for AutoVIDC (used by ADFFS on A-series) and EGA on VGA timings (used by ADFFS on RPC)
- Switched back to original MusMod2 on A-series to reduce T1 drift cause by QTM
