SaxxonPike d39f3e2e61 6502X: pending IRQs are not delayed when !RDY is asserted 2019-07-13 12:31:09 -05:00
SaxxonPike bf2cba0e23 6502X: remove a comment (this is indeed a dummy fetch) 2019-07-13 11:38:03 -05:00
SaxxonPike 9758efe604 6502X: CPU does a read or write regardless if the result is trashed, even during reset and dummy pushes 2019-07-09 19:46:33 -05:00
SaxxonPike 3efea15038 6502X: When !RDY is asserted, still do other operations. Plus, do dummy reads on stack ops 2019-07-09 05:24:47 -05:00
SaxxonPike d48964b642 6502X: According to the datasheet, RDY must be high in order for interrupts to trigger
- this has implications for C64, as it may cause VIC interrupts to fire quite later than they currently do

Scepheo f3ea6fe025 Use generic interface type on MOS 6052X for talking to the emulator core (#1189)
* Use generic interface type on MOS 6052X for talking to the emulator core
* Change CpuLink constructors to not use expression-bodies, to get the AppVeyor build to pass.
* Add comment explaining why IMOS6502XLink exists.

feos 09d765e853 make 6502 tracelog less bullshit
- stop spamming ---
- stop acting like 6502 is able to execute the same pc twice in a row
- put as many raw bytes as 6502 fetches per instruction
- reorder some registers
- stop being called when there's nothing to disasm
