Re: ADFFS 2.84 public beta

ADFFS build updated in the OP. Use with caution as it has not been tested to any extent. Two notable changes: Palette changes are now Gamma corrected SWI raised via OS_CallASWI/R12 are now checked for SWI that need to be intercepted for ADFFS to work It's the last of those changes that I've not test...

Unlikely I'd say, unless the source code is provided to me.

Probably a question to ask on Stardot, or ROOL if it's sourced via PackMan.

Re: Speed and sync issue in games

Some games that I wanted to back up and transfer to PC ended up with the 68e extension (or file type) and when I put them back on risc os and arcem, I couldn't access them anymore. If you need to transfer files via a host OS, ZIP them within the source RISC OS machine first (using !SparkFS ) to ret...

Re: Speed and sync issue in games

This works just fine with some games It will only work with games that either call OS_Byte 19 to wait for the Vsync, or use OS_Byte 112 to bank switch. All other games are covered by patches in the ADFFS Boot scripts . Flashback is not responding at all and the sound is still out of sync. You can r...

Re: Speed and sync issue in games

You should be using PackMan on the Pi to download the pre-packaged games. They will all run at the correct speed and you'll also be able to use a USB Joystick, such as an XB360 controller. For the games that aren't sourced via PackMan, you're more or less on your own, but I'd suggest installing them...

Re: ADFFS 2.84 public beta

I have a Pinebook Pro and have had a bit of a play. I am currently running the Sound /PCi beta Rom from RCcomp. (I think the PineA64 Rom on ROOL is for the original Pinebook and not suitable for the Pro and so have not looked at that) If the Pinebook Pro OS build is closed source, you would have to...

ADFFS 2.84 public beta

This update no longer requires EDID to be disabled ("disable_mode_changes" no longer required in CMDLINE/TXT) on a Pi as it uses GPU overlays to upscale the image. It might also work on OMAP (untested) and other GraphicsV drivers that support hardware overlays. Because of this issue on the...
