Re: QL Holiday cards

I kept searching for the GOTO that would go to these...but in the end, just left them in. Now I noticed a problem: at line 280 you allocate memory using RESPR - Memory allocated using RESPR cannot later be released So change line 280 to: 280 grinch=ALCHP(6400): backgrd=ALCHP(3200):bomb=ALCHP(84) An...

Re: QL Holiday cards

Nice work, bwinkel67! i have some remarks: - line 150: device should end with an underscore - add a speed variable and add line 545 Pause speed (otherwise it is too fast to run in QPC or even on GC/SGC) - line 1390 STOP never gets executed (which is rather a good thing, it should't be inside the pro...

Re: QL storage solutions: Pros, cons and opinions.

Hi - Here's my own take: Microdrives NO - the cartridges are old, the tape is unreliable Microdrive modern replacement YES - i use vDriveQL when I want to play old games. Most old games require JS ROM and will not run on a QL with more than 640K, some of them only with 128K. And no drivers or toolki...

Re: QL Holiday cards

After that I'll see if I can use Andrew's sprite technique to write a game. Might do it in C though. Might look at PETSCII Robots, though that requires the whole screen to scroll. Scrolling the whole screen on an unexpended QL requires some routine in assembly - BASIC or C are too slow for this, ev...

Re: Sprites on QL

.Why is Santa_spr twice the size of what the 13,600 half bytes would yield (i.e. 6,800). Just a bit confused by that. Because at that time I considered using a mask to allow for transparent sprite. So each frame has space for the sprite + mask (68x25 sprite + 68x25 mask) I ended up not using the ma...

Re: Sprites on QL

Thank you for the reply. I'm specifically curious about how the sprites in this Christmas card were created: The BASIC code loads _spr files for both Santa's sleigh and the present and uses a Turbo Toolkit call of MOVE_MEMORY to move the sprite. Both are using more than 4 colors. How were these cre...
