ADFFS 2.50 beta

Post by JonAbbott » Thu Jun 18, 2015 1:36 pm

Pac-mania music is now corrected on the Pi and No Excuses and Rockfall no longer randomly crash. The Arc/A3000 Christmas Box: Zap the Red Weirdos from Mars, Bubble Fair, Fire & Ice, Fish!, The Legend of the Lost Temple, Lotus Turbo Challenge 2, Maddingly Hall, Nebulus, Poizone, Rotor all work on the Pi. A big thanks goes to Steve Harrison for coding the QTM shim Module for the Eterna titles at really short notice and @Vanfanel and @ringdings for many hours of testing.

There's been extensive underlying changes since 2.47, page zero read/writes are now translated which has highlighted lots of bugs in games, as a result many existing game bugs are now fixed by ADFFS on-the-fly, including programming bugs and inadvertent page zero access - around 50 bugs in total, but we may not have found them all. Should you see an ADFFS abort screen showing an unhandled read/write in page zero, please report the address and info on how to reproduce the bug so it can be looked into.

Pi requirements:
  • RISC OS 5.21 RC14 or newer. ZeroPain builds (5.23) are not currently supported
  • AnyMode must be installed in !Boot.Choices.Boot.PreDesk or the monitor set to Auto in Configure
  • Ensure fake_vsync_isr=1 is uncommented in !Boot.Loader.CONFIG/TXT
  • SparkFS must be loaded
  • (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

RiscPC requirements:
  • 32mb minimum of RAM, slightly more for StrongARM based machines
  • RISCOS 3.71, 3.80 or 5.21. Many games will fail under RISCOS 4.x due to the way it allocates screen memory
  • SparkFS must be loaded

Changes since 2.47
  • See Changelog in the !ADFFS directory

Known issues
  • Doesn't support the protection used by Chequered Flag (non-RO3 version), Fine Racer and KerBang! (they talk 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 RPC and Pi the scrolling isn't quite correct
  • Does not work on a RISC OS 3.1x machine with more than 12mb of RAM
  • RO5.x IOMD doesn't support direct access to VIDC1, VIDC20 or IOC
  • Some games don't display on Kinetic (eg Zarch)
  • No 26-bit module support on 32bit OS's
  • Requires 30mb of free memory to work on a StrongARM machine, if the game isn't natively StrongARM compatible
  • Does not work on Iyonix
  • OMAP3/4 untested and may not work
  • Sometimes reports "Broken directory" after loading (exiting and reloading is a temporary fix)
  • Can't change discs in Apocalypse on RO4
  • ADFFS doesn't reset itself after the JIT is shutdown when a game quits (quit and reload ADFFS before trying to Boot another game)
  • The blitter doesn't currently support hardware pointers, so the ship and highscore will not be visible in Caverns on the Pi
  • On the Lemmings title screen, the mouse cursor corrupts as it goes off the left of the screen
  • Caverns doesn't display correctly
  • Krisalis Collection, The: Terramex hangs on the option screen
  • Missile Control the logo is too large and covers your score
  • Thundermonk fire doesn't appear on the Pi
  • The cursor is visible on the screen in Bubble Fair
  • The JIT doesn't currently work on physical StrongARM, ARM610/710 so many of the games detailed below wont work on these CPU's

NOTE: You must have !SparkFS loaded and use "Boot floppy" to run a game. If you don't, you could end up with a machine that isn't bootable, as some games try to 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.
