Re: My listing is eating itself...?

Are you loading any SuperBASIC extensions, or other machine code stuff. That's the kind problems you can get if the maths stack gets messed up. What you can get, is like a time bomb. If the maths stack gets messed up, every thing seems OK for a while, then BANG, things fall over nowhere near the act...

Re: Sam the Little Spaceman

Here is updated MDI driver. I have done a quick test on the CONVERT2_MDI command. But it seems to work OK in Qemulator with JS and Minerva 1.98 ROMs. It looks like I also did a fix for a block checksum problem in the FORMAT routine some time ago, But I don't remember doing it :) If I use the ROM ver...

Re: Sam the Little Spaceman

Just checked my QDOS Companion too. My notes for IO_OPEN (Page 39) are as follows: ⋅  D2 may not be preserved on exit. See QL World, December 1986 Page 43. ⋅  A1 is not preserved unless a TRAP #4 was done first!!! It seems I had problems too, some time back. Cheers, Norm. There ...

Re: Sam the Little Spaceman

EDIT. I don't know if it's just a typing error here, but I think the games filename is 'littlsam.mdv' not 'littlesam.mdv' I called it littlsam.mdv to keep it in 8.3 character form for when I copied it over to the fat1_ of my Q68 after dumping on the real QL! I did rename the filename to the correct...

Re: Sam the Little Spaceman

I believe it fails because of the dot in win1_littlsam.mdv. QL doesn't like dots in filename and gives a NOT FOUND error message. QPC2 is automatically changing the dot to underscore and that is why it works. Not quite, renaming tge MDV fille to "LITTLESAM_MDV" and usint the MDI command: ...

Re: Sam the Little Spaceman

Hi, On my QL Tetroid Trump Card with CF interface, Minvera v1.98, with Toolkit 2 enabled, I tried to convert the "Littlsam.mdv" file to MDI format, using the CONVERT2_MDI command. CONVERT2_MDI "win1_littlsam.mdv" TO "win1_littlesam_mdi" the command fails and gives a NO...

I decided to see if I could run the game from the MDI driver in Qemulator.
So I set Qemulator to 128K mode, and used the ROM version of the MDI driver.

Re: Sam the Little Spaceman

OK , I have had a look at the MDIConvert SuperBASIC program. It does fail with a 'Unexpected data in header" error. This was due to the program not knowing about Qemulator MDUMP2 image files. I have done a fix in MDIConvert3_bas MDIConvert3.zip I then ran the program in Qemulator (JS ROM) and c...
