Re: Show previous instruction for breakpoint in debugger

And it's a first instruction of some block of code. So I may suspect some JP or CALL was before it. But how can I find it without crazy guessing? Does any emulators stores adresses of executed commands in some log so I could check the log and find a few instructions before my breakpoint? Thanks for...

Re: ZX Spectrum Next

The next is far from finished, even when the cased units ship work will continue on it. Comparing it to something that's been out for near a couple of years now is a bit silly. I find the comparison interesting, at least while I'm waiting for my Next ;). Anyway, you have a good point concerning the...

Re: ZX Spectrum Next

Thanks for the link. I browsed that thread, but missed that particular discussion. Anyway, I suppose I was a bit naive, but the Next kickstarter could have been more clear on the subject of compatibility. I realise that it probably is no big deal for the vast majority of users.

Re: ZX Spectrum Next

Cons: Somewhat bad compatibility, and gets worse using HDMI due to timings. A lot ot things don't work or have some glitches (Nirvana engine games, demos with strict timings). ZX-Uno is miles ahead in this regard. Can you elaborate on the compatibility issues, and in what way ZX Uno is better? I'm ...

Re: Emulator integrated with Pasmo assembler

Breakpoints are now created automatically from labels named 'BR1', 'BR2' or 'BR3' (there are only three breakpoints in the debugger). After loading a source file with breakpoint labels, the user has to activate them in the debug window - (I may add an activation button in the assembler window later)...

Re: Advice on the sweet setup for programming on the Speccy.

My advice, and this is from experience, is not to touch White Lightning, as trying to program anything in Forth will drive you mad. I have the same experience :lol:. White Lightning seemed so promising. I remember watching the demos, thinking that now I'll finally be able to write that elusive bloc...

Re: Emulator integrated with Pasmo assembler

Very nice! Thank you :) Even better would be if you could set execution breakpoints in the emulator using comments in the asm source. I think it would be difficult to set breakpoints using comments in the source as long as I let Pasmo handle the assembly; the emulator never sees the source, and the...

Re: Emulator integrated with Pasmo assembler

I made a little experiment and let the emulator load the symbol table which Pasmo generates into the debugger, like this: https://s22.postimg.cc/fxjpwgv19/Symbols.png The symbols are stored in an array in parallel with the memory array. It would be nice to pre-load the labels from a ROM disassembly ...

Re: Testing emulators using z80test-1.0. Quck results

Nice work. I'm testing your emulator and I can say it looks promising. It plays the Gyroscope music quite well, something not all emulators are able to do. I can't hear any specially hard to emulate on Gyroscope music. It's a simple tune, really. From my POV emulate Fairlight, Sidewize, Cobra, Mad ...
