Running this on VICE and I'm loving it! I had some stuttering problems with GTKVice, but fortunately realized that there is a daily build link available, from which you can download the SDLVice which at least for me, works almost lagless. There is still some fairly rare random stutteringings but I almost quit playing because of the stutter on GTKVice, and with SDLVice I don't mind it at all so...
Anyhow, are there any recommended settings to use? C64 vs C64C? PAL vs NTSC? etc.
EDIT: I noticed there's this weird, high pitched pop when jumping around and it happens prominently when emulating PAL, when emulating NTSC it happens too but rarely.
