Broken graphics in twinbee #312

Closed Barbe86 closed 2 years ago

Barbe86 commented 2 years ago

This issue happens when you play the first twinbee game.

When you reach the stage 4 and 5 the graphics start to mess, specialy some enemies and backgrounds. I've seen this exact issue in the 90's when a played this game in a NES clone with a multi-cart, I think there's some konami chip in this specific cart that is not reported.

Thanks IMG20220425225344 IMG20220425225656 IMG20220425225858

Please send a save state. I will check with my rom, thanks.

I made a savestate when graphics start to mess, the game is paused. Link to my dropbox to download: https://www.dropbox.com/s/oiivbg1h5jp7230/TwinBee%20%28Japan%29_1.ss?dl=0

Just tried your savestate with my 2.0 rom and not seeing any visual glitches. It looks like your rom has a bad header. This is a pretty common issue with many roms that were made to work on software emulators. I'd recommend just grabbing a 2.0 set somewhere.

I will try ASAP. Other weird thing is that the FDS version it gets black screen when you reach the stage 4.

Solved. I tried a different rom and it worked well. Thank you!
