The Sinclair QL Forum

Don't forget the STOP instructions halts DSL activity and that is used by Trump Card (maybe also GC/SGC?) for DRAM refresh. Would that also effect a Tetroid QBIDE with an on board RAM upgrade? I think that is what Nokosdoykas is using. (I don't know about Cristian) I might try NOPing out the STOP c...

I'm curious to know why one would need a blank FLP image file. Why not just use a QXL.win file? Are these microdrive and floppy formats particular to just Qemulator and Qlay? I've used floppy image files, but these are direct copies of a floppy using 'dd'. Tim The FLP images are essentially the sam...

Image File Utilities is a group of SuperBASIC extensions for handling microdrive and floppy disk image files. It can create microdrive images in Qlay, Qemulator and MDI file formats. And also convert existing microdrive image files between the three microdrive file formats. It is still a work in pro...

This game crashes on real QL (both JM and Minerva). QL freezez with black screen before the options menu. :( I have only run the program on emulators, but I did notice that it does something that looked odd to me with I think it was the STOP, command. If I correctly understand what was supposed to ...

Increasing the EHT will make the picture smaller, as the scanning coils will have less time to move the electron beams side to side, and up and down. Also for anyone who's thinking about trying it. There's is a lot more than 250 volts lurking around there, more like 25,000 volts. Even when switched ...

Here's a patched version the the game, without copy protection, and it should work OK from a directory. (A bit hard to test, as I can't do directories in Qemulator, and the game does not like QPC2 very much) Edit the path$ in line 100 of the boot program to where the files are stored. The high score...
