Embedded SCPU64 ROM V0.07 (free replacement by Soci/Singular, 64 KB), chargen
|
|
(901225-01, 906143-02), C64 BASIC (901226-01), all C64 kernals (Rev 3, GS,
|
|
SX-64, 4064, Japanese), all drive ROMs (1540 through 9000), and VIC-II palettes.
|
|
Embedded ROM check in sysfile_load takes priority over filesystem. External
|
|
scpu-dos-*.bin provide the original CMD SuperCPU DOS kernals, loaded from
|
|
system/vice/SCPU64/ when SuperCPU Kernal core option is changed from Internal.
|
|
JiffyDOS requires True Drive Emulation enabled and a non-internal SuperCPU
|
|
kernal (the internal ROM is not JiffyDOS-compatible). The .info incorrectly
|
|
declares JiffyDOS_C64.bin (firmware_count=4); the C64 kernal replacement is
|
|
only loaded for x64/x64sc/x128, never for xscpu64. Correct firmware_count=5
|
|
(2 SCPU64 kernals + 3 JiffyDOS drive DOSes).
