NES 2.0: mapper 355
- In MESS: Very Preliminary Support. What is the purpose
- of the writes to $4800-$4900-$4a00? These writes
- also happens on the RCM version, which however works
- (probably an unused leftover code in that version)
+ In MAME: Not supported.
- FCEUmm suggests it might be IRQ related, but
- it does not seem to help much...
