Brendan Robert has released a new and improved version of his Java Apple II emulator.
] 65c02 CPU emulation is now 100%, tested and verified thanks to Klaus Dormann’s test suite: https://github.com/redline6561/cl-6502/blob/b008…nctional_test.a65
] Overall CPU usage is way down thanks to recent changes:
Video generation rolled into main thread and this made things a lot more efficient
Switched to older timer model, newer lock-based timers were considerably slower
Memory listener model streamlined to be more efficient
] Skyfox now detects mockingboard in slot 4
] Pitfall II detects mockingboard and plays perfectly!
] Disk II speedup hack now provided as a configuration option (previously, speedup hacks were always enabled to max the emulator speed when disk is in use)
] Hayes smartmodem now has UI activity indicators
Some folks reported in the past intermittent issues where the emulator would hang on start and never actually begin executing the rom (symptom: Screen with alternating checkerboard and inverse @ symbols). I believe this release fixes that problem once and for all.
This is the most stable and efficient build to date, I hope it is useful to your folks!
