Re: ADFFS 2.41 on the Pi 2 running RiscOS 5.21 help needed please

Are there differences wrt alignment exception handling and deprecated instructions? Yes, there's a number of "implementation defined" instructions and some behavioural differences with instructions. For example, LDR R0,[R0],#0 may work on one chip but generate a fault on another. Other examples mig...

Re: ADFFS 2.63 beta

Power issues? I seem to recall they have different SD controllers, which may also be a factor.

Re: Resurrecting the original ArcVenture series

If you're going to the RISC OS London Show, I can image them for you there.

If you could PM me the contact details for Sherston, I'll have a conversation with them about releasing all their Archimedes titles.

Re: ADFFS 2.63 beta

New build up on the dev site, I found some fairly fatal bugs whilst testing on the Iyonix. There's still some lurking, as some games are still failing. @jon: try to move the mouse in circles, doing it on the main menu will do. What's the SD card you are using to store the CUE/BIN? Brand, class... I ...

Re: ADFFS 2.63 beta

I've play tested it for hours on a Pi3 with no noticeable mouse problems, I'll try Pi1 and Pi2 when I get around to building them for the London Show

Re: ADFFS 2.63 beta

However, it seems to have problems reading music: the cursor becomes very "sticky" when the SD card access light comes up. No way around it? (Keeping the great audioCD OST) We have SO much RAM on the Pi2/3 that almost all the CD could be in cache :lol: As I warned you, I've yet to optimize the audi...

Re: ADFFS 2.63 beta

I've tracked this problem down, !65Host is attempting to directly write to the OS_Byte variable table. I'll probably botch it for the time being as its not going to be straight forward implementing a Page Zero read/write translation to the equivalent OS_Byte call. Updated Modules on the dev site wh...

Re: ADFFS 2.63 beta

@Jon: How can I find out the correct partition number? Is there a RISC OS console command to list partition numbers? Plug it into a PC and look in Windows Disk Manager or use a Linux equivalent, RISC OS doesn't understand partitions. There is an issue affecting Zalaga, but I believe that's specific...

Re: ADFFS 2.63 beta

- "Hero Quest" has stopped working (from floppy image and HDD install). Stalls on a black screen with white cursor. - "The Cobalt Seed" has also stopped working (a great game, this one!), crashes as soon as launched, with a Data Abort exception. - "Wolfenstein 3D" hangs the whole system as soon as ...
