r9262 /src/mame/drivers/megadriv.c: [32x]: Hooked up RV bit, NBA Jam TE uses it for banking the ROM on 68k space

It actually die due of missing EEPROM emulation (should be hooked up at 0x200000), debug tricking it and you can see title screen and team menus ... gameplay doesn't work due of unknown reasons:

Fixed Spiderman Web of Fire 32X

It seems to be a 2-part problem, there was a bug in my alt priority scheme rendering, AND (this is what was confusing matters) the game writes an invalid priority setting with the 68k, which then gets picked up and used for the rest of the game.

It appears that the 68k does not have VDP authorization when it does this, and that write should be ignored. I'm assuming it's buggy code and ignoring it is correct behavior.

(and yes, you can play with spiderman on the Sega logo)
