Weird issue (U2+) Cartridge on C64 Silver label. #439

Open 0wwafa opened 2 days ago

0wwafa commented 2 days ago

I have tried a few cartridges on the U2+ and they all seem to work on the breadbin. Today I found out some cartidges I made, work on the breadbin but not on the silver label. It's not about ROM differences between the two.

They are both magic desk type.

I have no idea how to debug this because in the emulator(s) they both work,

archon.zip

Attached are the two cartridges. Any help apreciated (if it's my fault) if it's not.. then it's on you :D

It looks a bit like #335 on my U2+

Have you tried adjusted PHI1/PHI2 settings for that Silver Label ?

radius75 commented 1 day ago

This is probably not a problem with PHI, I have the same problem with Archon as OP.

Yep. I tried every possible setting of PHI1/PHI2. Probably it's because my cart loader is the fastest possible.. but I don't yet know if it's the cart loader that causes the problem or the U2+.

Hmm.. I did not test it with 3.9... I am on 3.11 now.

Archon 64KB crt doesn't work on fw3.9 for me either. So it probably never worked.
