Describe the bug TwinBee: Stage 4, 5 doesn’t change CHR bank so everything is mess. Lot Lot: The music doesn’t play noise drum.

To Reproduce

Running TwinBee and Lot Lot good dumped ROM in GoodNES.
Play former to stage 4, play latter just in main game.

Expected behavior TwinBee see different enemy graphic and correct ground in stage 4, 5. Lot Lot hear the music’s noise drum.

stage 4 in twinbee has always been a glitch as far as i remember. even some sample vids on TY claiming that its running on "real hardware" also has this glitch. there are some vid with better looking stage4 but not sure if this is a different rom revision/variant.

Your ROM's ines header is incorrect

Theoretically, yours is not mapper 87

twinbee real hardware Original or complete piracy run not have this issue, Most Multicarts have 8K less CHR

Interesting. Modify mapper to 87 manually could make it change CHR bank as it should. In GoodNES, TwinBee (J) [!] ROM is mapper 3, some emulator could run it normally though.
