Having used my AVS for two weeks now and played with updating firmware and testing various cartridges there are some issues with how the Everdrive N8 and AVS interact that I am starting to see. Castlevania 3 worked just fine out of the box on the AVS and on all firmwares up to 1.20b3 confirmed via Everdrive. However I am now experiences problems with the Everdrive. It plays everything else I throw at it just fine except these two games:
On firmware 1.20b4/5 Akumajou Densetsu expansion audio is all jacked up and there is a persistent graphic glitch along the top bar of the screen while playing. Rolling back to 1.20b3 fixes both of these issues.
After updating to 1.20b5 I tested Castlevania 3 via Everdrive and actual Cartridge. My Castlevania 3 cartridge loads and plays fine on AVS. Everdrive Castlevania 3 has graphic glitches everywhere, and graphic scrolling appears to not even be functional. You can't see where any of the level is. Reverting back to older firmwares does not fix this issue. Even back to AVS 1.10.
I have tried reformatting and reloading all my roms and os software for the Everdrive. I tried everdrive OS v12 and v13. I have tried multiple SD cards and the ROMs from four different sources. Originally working was the smokemonster romset, but this CV3 rom is now glitchy also on the AVS. Tried GoodNES, no-intro, etc... all without any change in the graphic/scrolling glitches. The ROMs and Everdrive all do work on my AV Famicom without the same graphics problems. So I know for sure the issue lies with how the AVS and Everdrive are interacting.
Can anyone else confirm these issues? One user on Nintendoage confirmed the issue with Akumajou Densetsu, but did not test CV3. Anyone know of a fix? Is this something that can be patched on the Everdrive side?
