ADFFS 2.69

Post by JonAbbott » Wed Nov 07, 2018 1:25 pm

A minor update to bring in sync with the PackMan distribution.


A305/A301/A410/A440/A540 requirements:
  • 4MB RAM minimum, 12MB RAM maximum
  • RISCOS 3.11
  • ADFFS must be installed to a hard-drive
RiscPC requirements:
  • 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 4.x due to the way it allocates screen memory in 1MB blocks
  • NOTE: Some RISC OS 4 builds (4.39 for example) have an inbuilt version of ZLib which contains a compression bug. You must *RMUnplug ZLib from the ROM if you wish to save/image JFD files
Iyonix requirements
  • RISC OS 5.23 Jun 9th 2016 or newer
  • To get legacy TV MODEs working (0 to 15), you can try this Monitor file for 75Hz EGA on VGA
    EGAonVGAMonitor.zip
  • (optional) For USB Joystick support, load the USBJoystick Module and configure the Joystick mappings with *USBJoystick_Map, before running a game via ADFFS
Pi requirements:
  • Any revision Pi, from Pi 1 to Pi 3 Model B, including Pi Zero
  • RISC OS 5.23 Jun 9th 2016 or newer
  • AnyMode must be installed in !Boot.Choices.Boot.PreDesk
  • Ensure fake_vsync_isr=1 is uncommented in !Boot.Loader.CONFIG/TXT
  • If you're running a ROM build of 14th Dec 2016 or newer you must disable GPU mode change support by creating !Boot.Loader.CMDLINE/TXT with the following contents:

    Code: Select all

    disable_mode_changes
  • (optional) For USB Joystick support, load the USBJoystick Module and configure the Joystick mappings with *USBJoystick_Map, before running a game via ADFFS
  • (optional) For the proper retro gaming look, you can 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:

    Code: Select all

    hdmi_ignore_edid=0xa5000080
    #
    hdmi_group=1
    #576p @ 50Hz
    #hdmi_mode=17
    #
    #720p @ 50Hz
    #hdmi_mode=19
    #
    #1080p @ 50Hz
    hdmi_mode=31
    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 difference

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 if an HD floppy is mounted on RO3.5+ ARM710 under RedSquirrel
  • Although Caverns runs fine under VIDC translation on the A7000, on a RiscPC the scrolling isn't quite correct
  • Some games don't display on Kinetic (eg Zarch)
  • OMAP based cores are untested and may not work
  • Some games that use overscan may result in a blank screen on a RiscPC
  • Vubars in Overload (2000) (Paradise Games) help pages cause a crash
  • 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 a task switch)

Changes since 2.69:
  • *TV setting wasn't being applied on IOMD RO5
  • removed VSync_at_Key_Scan code
  • OS_ClaimDeviceVector SSBC tracking was causing a hang on IOMD
  • Autoloads USBJoystick on RISC OS 5

NOTE: 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.

Re: ADFFS 2.69

Following on from my earlier issues with crashes, I thought I’d do a spot of re-testing. I’ve updated my Pi B+ to the firmware from 5th Nov and RISC OS 5.27 (built 16 Nov). I have tried using ADFFS 2.69 and 2.70b, but I can’t get Pacmania, E-Type or Saloon Cars to run at all.

With previous versions of RISC OS, Saloon Cars would clear the screen and say ‘Please insert the original disc, press SPACE or click mouse’, so I would press SPACE, and see it load. Now, the message isn’t printed on a clear mode 13-style screen - it is just painted onto the desktop. If I press SPACE, then it says ‘not enough memory to change to this screen mode’ and stops loading. If I try again, I get ‘Abort on instruction fetch at 01A04454’, then similar at 011FF54C. I have to hit CTRL-BREAK at the point, as the machine becomes very unstable.

Pacmania doesn’t load. It prints ‘not enough memory to change to this screen mode’ onto the desktop.

E-Type doesn’t load. It displays the E-Type silver graphic, then freezes.

I suspect that Jeffrey’s latest round of graphics code updates (which I think are related to mode changing!) are causing an issue. I’ll ask on the ROOL forum, as even basic stuff like F12, BASIC, MODE 12 doesn’t work (it says ‘screen mode not available’).

I’ll try and look into it a bit more with an older version of RISC OS (prior to Jeffrey’s changes).

@Jon: I have found some regressions:
-Hero Quest hangs on language selection screen
-James Pond 2+ causes screen corruption on exit

Your suspicions are correct, ironically those changes are the first part of a reimplementation that came off the back of issues I reported whilst coding the legacy MODE support in ADFFS. I'm not sure if it's one issue or several as DA2 memory allocation doesn't appear to be working.

Speaking of regressions, with USBJoystick loaded (any version) and no Joystick attached (haven't tried it with one attached), load Pacmania [learning curve version] and watch the level selection screen go nuts when you try to start a game. I believe it's using the Acorn interface, so is possibly getting rogue values causing the selection to change.

I couldn't reproduce the issue with JP2+ (tested on 2.70b) but did reproduce the issue with HeroQuest. Now that's odd, because I was using HeroQuest to test the changes to DiscOp\MiscOp in 2.70b and it was working perfectly. I've had to go back to 2.66j before it works reliably, so will investigate further. It's actually reporting an undefined instruction after selecting the language, so it's possibly some self-modifying code running under IRQ/SVC causing the issue.

EDIT: HeroQuest also works with 2.68s but not 2.68t

The only change between 2.68s and 2.68t was the VCHIQ locking issue fix in the GraphicsV driver, so its possibly a timing issue around VSync that causing the lock.

I suspect the game is getting into a race condition as it doesn't actually hang, I believe its stuck in a tight loop waiting for a memory value to change. I'll probably need to dump the game code and modify it, as I've no idea when the VCHIQ issue will be resolved in the OS.
