Re: QL Games/Software on mdv Cartridge.
Btw, I have a copy of Vroom that I bought for pretty cheap at RWAP when I was getting a keyboard membrane. I haven't been able to get it to run successfully. On my BBQL it starts the game but freezes. I tried to run it on Q-Emulator via the floppy drive, and no success. Was Vroom write-protected? Co...

Re: QL Holiday cards
Using Andrews code I created the following Christmas card for 2023. It's not complete as I want to add some blinking lights and have lights in windows go on/off, maybe have the Grinch drop a random amount of bombs, not all four each time. Once I finish it I'll include a zip file with the BASIC code....

Re: New microdrive internal replacement
...and as Peter alluded to, emulators are really nothing more than fancy interpreters. I've written both...not only the ZXSimulator which is a ROM emulator (i.e. that is really an interpreter that mimics the interpreter of the original ZX81) but also true processor-based emulators. They all take the...

Re: New microdrive internal replacement
Well, the sampled Microdrive sound used can be found in the source code: https://github.com/stephen-usher/vDrive-Sound-Board/blob/main/ATTiny85/mdvsnd-v1.ino I need to implement your solution. I bought the same thing that Noel did and its scraping microdrive sound was pretty bad so I uninstalled it...

Re: New microdrive internal replacement
Exactly what many solutions do using FPGAs. Interpret what it should do since... you have not the original logic schema (technology, context (voltages, etc)) or somebody try to reproduce as close as possible the "real/original" behavior. POVs of view, if for you FPGAs is same than origina...

Re: Sprites on QL
Ah, that makes sense. I really like your Sprite-like mechanism. I'm wondering if MOVE_MEMORY can be replaced by an inner for loop if compiled. I'll have to try it since, in BASIC, that inner for loop runs really slow. But with this technique it would be pretty easy to create a game in BASIC. The ani...

Re: Sprites on QL
I was able to convert it to half its size and it still works. santa2_spr.zip I wrote a little BASIC program to do so: 10 REMark loads original sprite 15 PRINT #0, "Loading original Santa into memory.": a = RESPR(13600): LBYTES win1_santa_spr, a 20 REMark now generate new sprite using half ...

Re: Sprites on QL
I simply used Photoshop to create the sprite sheet, saved is as a RAW file that uses QL mode 8 pallette, then converted it in QL screen format. There is a sprite sheet for the owl's blink and one for Santa. The gift box is just an image (only one frame). Keep in mind that my sprites are NOT the sam...

Re: CPLD replacement for ZX8301
I just saw this 8-minute video (posted 8 months ago) by Danieel Terdina about an FPGA replacement for the ZX8301 he was designing:
