My latest SP-2-MC10 took me about a month to code.
It is a TRS80 MC10 emulator that runs ON a ZX Spectrum.

I don't think you need to test he "(" in DEF FN since the BASIC does the syntaxcheck on entry.

Re: Zilog's Z80 opcode choice
DEC SP/INC SP are silly instructions too. It would be loads better if it decremented/incremented by 2, changing by 1 has no use I can think of, since you always push a word to the stack. If it incremented by 2 it would just be like discarding the value on the top of the stack (I usually use POP AF ...

The CSSCGC can never have enough simulators.
I think that each year has at least 1 simulator.
I even won once with a simulator as did other simulators.

Re: How big should new Speccy games be? 48k? Bigger? Release 2 versions?
My ACES project started in 2011. Got a hard bug that stopped the project. In 2016
the bug was solved but the original idea is partly lost.
Still did some progress but project is again on hold since 2020.

Now reviewed some background info https://www.bbc.com/travel/article/20230522-the-dutch-solution-to-busyness-that-captivated-the-world BTW the screen is just a drawing from internet altered with software into a scr. The program took me yesterday evening. So still time enough to do nothing afterwards.

I downloaded it for a quick look and to add to the DB, and found myself playing a few games. That's a sign of a decent Minesweeper :) In fact this is a rare case of a Speccy licence that is mostly free of howlers. Quite a lot, it starts to look like BOMBER. All version (also the ZX81 version) can b...

You can use the memory tab and in the address input you can simply input the address and see what is there.

Re: PROJECT : A TRS80 MC10 emulator on the ZX Spectrum
Oh, thank you! That's exactly what I was suspecting, so I guess I'll quit Spectaculator and download ZXSpin instead! :) Or find out how Spectaculator works with tap-files. I can do the same with other emulators. In my video how 48 KRAAK works I use Z80. https://www.youtube.com/watch?v=j9O53I4tlTU

Thank you for this I have it partially working. I can’t get it to work at all when I launch Spin using Notepad++ macros to both assemble the opcodes into an .asm file using Pasmo assembler and then launch spin and automatically load the asm file. I can use it if I load that same file produced by Pa...

Re: Looking for bedroom coders / developers who in the 80s worked on ZX Spectrum or Sam Coupé games
I coded many games but nit really released.
I gave copies to friends but that is it.
I made 48K Kraak which was for sale on a local market for a while but no official
softwarehouse for the release.
With internet I coded more games and now today some games are still for sale at cronosoft.

Re: The code so bad you won't hire
I once had to test a system as a user. In a database: You could do a selection and a sort. The programmer first did the sort and then he selected the items he needed. I suggested to do it the other way around, thus only sorting the selected records. He was not amused and asked if I could be taken of...
