/* ASIC ROM numbering system */
*ROM 7: Burnin' Rubber ROM 3
Also, physical ROM 1 is mapped to logical ROM 0 and . And on 6128+ only, physical ROM 3 is mapped to logical ROM 7. The ASIC is configured not to map AMSDOS on 464+ and GX4000, even if a 6128+ cartridge is inserted.
Logical ROMs can be replaced by using a [[ROM board]] while physical ROMs cannot be replaced.
