r7766 /src/mame/machine/snes.c: [SNES]: Fixed a bug with un-inited DMA regs, fixes at least a long-standing bug with Super Soccer dimmed team selection screen




It does:

8f90: lda 420c <- open bus read, A = 0x42 ...
8f93: and $fb
8f95: sta 420c <- ... hence it enables HDMA channels 1 and 6, channel six is uninitialized and it was writing shit to the INIDISP register


Is it normal that anything that doesn't work in the SNES driver is actually caused by HW bugs rather than missing features? --"
