Re: ADFFS 2.84 public beta

Updated build in the OP with adjustments to the way overlays are created and updated, so it now fully complies with the restrictions on overlays. Despite the changes, I'm still seeing overlay issues that I've previously reported (ie machine locks, overlays not being displayed, banks not being mapped...

Re: ADFFS 2.83

A question: Would it be possible to have PC-conversion games centered instead of them being displayed with a thick brack bar under the image? Not easily as that's how the games were coded as a straight conversion from PC versions. Its more noticeable on a 16:9 display because of the black bars left...

Should be fixed with the latest obey.zip

I've also back-ported the bugfixes to RISC OS 3.1x and added a timed delay to level selection screen, which was previously CPU speed dependent.

Re: ADFFS 2.83

Are these dispmanx-managed overlays as in old days GNU/Linux Pi1/2 graphics? They're GraphicsV overlays, which in the case of the Pi are handled by BCMVideo and passed through to the GPU via mailboxes to the Pi firmware. About the scaling issue: Games like Alone in the Dark, GODs, etc.. have a thic...

Re: Verfiying JFD Images

That's expected behaviour, when imaging it only stores sectors that contain data and I've yet to add the code to ADFFS that will dynamically create missing sectors when they're touched...so you'll currently see disc errors if you verify a mounted image.

Re: ADFFS 2.83

-Alone in the Dark is indeed fixed now, no more palette problems! (But there's still an audio problem: effects pitch is too high I didn't get as far as playing the game...only checking the intro looked correct :roll:. the game seems to be "compressed" to the upper part of the screen. I've...

Re: ADFFS 2.83

-The Pac-Mania version which has problems with WiFi is FD1050700. I installed the Learnin Curve version instead (FD1044700) and it works fine with WiFi! Well that's odd, I didn't think they were that different. I'll see if I can reproduce it -I re-downloaded the Fireball I-II package from !PackMan ...

Re: ADFFS 2.83

-I'm already on Risc OS 5.30, installed from latest SD card image, so I don't know what's wrong with the certs, really. Maybe they are not updated on the 5.30 SD image? It might be an issue with RISC OS 5.30 as I first noticed it on a new build when testing Partition Manager. I manually updated my ...
