Amiga 1200 2B and using a CD32 controller..?

Perhaps some A1200 boards use a higher value capacitor than they should? It's the sort of thing that might not have been noticed during testing at the factory...

I'll be testing against every board that I recap from now on.

No harm Just remember though that those caps are small ceramic ones, not the normal electrolytic caps you'd normally change. They're down as 470pF on the A1200 Rev 1 schematics (and the A600), but 1000pF on the A500. I think I had changed them to 100nF on my machine, but I suspect anything over 1 or 2nF might cause issues.

Hi did anyone solve this issue via software ?

I have issue with whdload and game using cd32 pad. Most do not work properly using cd32 pad (even if cd32 version).

My A1200 is an Escom with a Blizzard 1230IV and has been recapped

"most don't work properly" ? what do you mean?

I must admit I never fully understood those pad problems. On my CD32 the pad worked fine whereas with the same game the game control failed on my A1200. Timing issues? well, possible (Bert fixed a timing issue in the CD32 joypad read routine, maybe the games you're talking about don't have the fix)

Sorry to bring this up again but did anyone find a fix ? I still have the Escom A1200 and still have the issue with some games giving issues with the CD32 pad.

Current CD32 pad I am using is the Competition Pro pad for CD32.

Some examples:

Bubba and Stix CD32 version: Two button pad selected, first button works but if I press the second button to jump it goes into an "autofire" mode and the player keeps jumping and the first button stops working. Directions work fine.

Street Fighter II: Directions work fine but the fire buttons are all messed up when selecting joypad.

I have even tried these (WhdLoad) games from Tiny Launcher without going into Workbench.

There are more games with CD32 pad issues but I cannot remember which ones right now. Then some will work completely fine.

I have had issues with certain versions of WHDLoad games with CD32 support (Virocop and Flashback are two of them) which exhibit similar issues to yours, typically resulting in no fire buttons working until the computer is restarted.

Changing to different releases of the slaves seems to resolve the issue for those games so you might want to check that if you haven't already.

you'll have the best chances by using whdload slaves. And report in mantis if you still ahve issues. We're beginning to have a good experience of what's working and what's not working.

For instance, I fixed some slaves which worked ok on CD32 controller but not on PSX+adapter... without even having a PSX adapter but just by guessing and from cross-reports from other slaves.
