The Sinclair QL Forum

Well, (1) quite busy with other things and (2) looking at X68000, a Japanese emulator in Java, emulating a popular 68000 micro in Japan. I'll be back.

Thanks for the support! I will be away on holiday in August, so I won't be back before September. By then, I think it would be worthwhile to make a kind of work breakdown structure with the focus first on the M68000 and then on the specific QL stuff

I discussed some bugs/omissions in the emulatorcode of m68k with the author. He was happy that actually somebody was digging into his code and suggesting improvements :D He is writing an Amiga emulator, and will do the bugfixing, albeit not on short notice.

Screen and keyboard handling is relatively straightforward to do in Java (based on what I saw in JZX and qlay sources), but I have some questions about some io registers (mdv handling, th...

Hi all, Well, I have been messing around with the M68000 emulator in the link I posted and within an hour(!) I had a booting JM.rom! However, it got through the memory check (so you can see the famous startup pattern appear and disappear as I had made a GUI based on the screen part of the memory, it...

Hi RWAP,

I googled "java emulator amiga" and I found this link: https://github.com/tonyheadford/m68k, looks promising! I'll have a try to see if it can read a ql rom without too may mistakes.
