** What's done
|
||
|
|
1) 65C816 emulation via lib65816.
|
||
|
|
2) Selected 65C265 features. (Can be disabled by undefining CPU65265 in opcodes.h.)
|
||
|
|
- 65C265 Vectors are implemented. (COP, ABORT, NMI, IRQ)
|
||
|
|
- Added some 65C265-specific IRQ sources and vectors: IRQT5, IRNE64.
|
||
|
|
3) VERA emulation via code extracted from X16 emulator.
|
||
|
|
4) Loading of selected BIOS ROM.
|
||
|
|
** What's not done (i.e. TODO List)
|
||
|
|
1) System timing. Emulation always runs flat out instead at stable 8 Mhz.
|
||
|
|
2) Clean up dispatch loop in dispatch.c for easier maintenance.
|
||
|
|
3) Keyboard emulation.
|
||
|
|
4) Timer emulation. (Start with timer #5)
|
||
|
|
5) SD Card emulation.
|
||
|
|
6) Audio emulation.
|
||
|
|
7) SNES controller emulation.
