Mean I correctly - VICE emulator?
If yes, we all will be happy if there will be C65. In other way I mean C65 will be there before SCPU128. SCPU64 there is, but sadly Commodore 64 is on the top and other computers like C128 are lower.
For example - many fixes, but long time existing FD-2000/4000 problem in case C128 was not yet fixed. All other computers with IEC bus can use FD-2000/4000.
How to programming M65 - as base can be MESS and its C65 emulator. Many meaning that works not, half is true - new versions of MESS working not, older yes.
Please forgive me (VICE developers) my critical words - really I never saw better emulator of C128 and other Commode 8-bits. But how to programming M65 before release? Easy - write code in MESS and test on Nexys4 - no problem. If you can, use 64TASS assembler.
