Re: ADFFS 2.70

Lotus Turbo Challenge 2 crashes on quit. It appears to have two illegal instructions in its Exit handler, I'll figure out a fix. Also, it's impossible to use the joystick in Lotus 2. As soon as joystick control is selected, the keyboard stops responding so there's no way to start the game... Once J...

ADFFS 2.70

ISO imaging added along with some changes to improve floppy imaging. This build corrects an issue that caused low bpp screen modes to fail on RISC OS 5.27 nightly builds, also note that AnyMode is no longer required on the Pi for legacy modes to work. Additional games now supported on RISC OS 5: F10...

Re: ADFFS 2.69

Spent a few hours recoding VSync generation in the GraphicsV driver yesterday and managed to get this title working...however, the knock on effect is Gribbly's Day Out, Manchester United and Manchester United Europe all break. Spent a lot more time looking at this on Thu and managed to get all four...

Re: ADFFS 2.69

Looks like the Learning Curve version added Acorn SWI support (I had previously been testing with the 1989 release). It adds JoyMod support. There's one SWI @ 409C0 which isn't getting a result returned from USBJoystick. I think you just need to return R0=0 if there's no Joystick attached to fix it.

I don’t see what you mean by ‘go nuts’.
Must just be on mine then. The selection page is cycling around the level options really fast, making it impossible to make a selection vie keyboard.

I'll breakpoint the code to see what Joystick_Read is returning.

Re: ADFFS 2.69

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 believ...

Re: ADFFS 2.69

I suspect that Jeffrey’s latest round of graphics code updates (which I think are related to mode changing!) are causing an issue. 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...

pi-topUtils 1.06

This build includes pi-top2 battery indication as provided by Timo Hartong. The HID driver has also been modified to support the pi-top2 keyboard, but is untested. If you receive an error reporting it failed to find the keyboard, please post your keyboard USB$Device value, so I can add it to the sup...
