Talk:Mask ROM pinout

I have two questions regarding to this :

1) Does anyone have the pinout for SLxROM and TLxROM boards ? Such boards were apparently rarely/never used in PAL games so I can't do much about it, unless I pay more than $30 to import USA games.

2) Apparently, the unused high address lines of PRG and CHR mask ROMs must be connected to VCC, but this was vital only on PRG ROMs as the CHR-ROM are not required to be enabled for booting, before the first mapper write. So, does games which don't use all their available CHR-space uses '1' for the unused bits ? For instance, a 32kb CHR-ROM MMC1 game should use either CHR bank range 8-15 or 24-31 instead of using 0-7 which would happen naturally, in order to set A15 to '1'. Does commercial games do this ?
