Re: QSTAR 2
I load a lot of programs residentially at boot. I tend to avoid programs that include Qlib_run, TK2, Turbo_TK, Ptrmen_cde, Qptr, .. as their inclusion doesnt bode well for the quality of the rest of the program! I tend to load those toolkits and a few more myself at boot time. That's what you and I...

Re: QSTAR 2
In most cases, it is just better to link TK2 (or any other used toolkit) into the compiled binary instead of loading it in BOOT. That means once your program is done, it will be gone again. With your approach, you might be ending up filling your memory with multiple copies of TK2 (which won't hurt, ...

Re: Double buffering?
Even if Peter says there isn't, here is a working example of how you can make the second screen usable in QDOS machine code programs. I didn't say there isn't. Just that I can not remember - which is a difference over 50 ;) I wonder how much room your procedure would leave for the actual code and d...

Re: Double buffering?
Even if Peter says there isn't, here is a working example of how you can make the second screen usable in QDOS machine code programs. Software that wants to do that needs, however, jump through some hoops to work and come back to a working system. You will also likely need a memory expansion to have...

Re: QL / PASCAL
Just as an info, maybe someone is still interested I definitivly am :) That was - at least in my opinion, and I think I deserve one :) - not exactly a bug in vlink , but rather was a missing work-around. It's an age-old bug in QDOS that it will allocate the stack of an executable whose load-size is...

Re: QSTAR 2
Dilwyn,
That's one of the (the main) reasons why I'm not sure whether the header preservation methods we have devised over the years are really of any help at all or just create even more confusion. I sometimes think it 's the latter.

Re: Plug-in ROM without $4AFB0001 Header
The EPROM was apparently used as a means of copy protection. Had I done that, I'd likely have coded the EPROM contents as position-dependent, which makes it next to impossible to simply load the EPROM contents to some other address and run it from there. EPROM_LOAD is indeed SMSQ/E only (to work pro...

Re: Plug-in ROM without $4AFB0001 Header
I was wondering if anyone could confirm, please, that if a ROM at $C000 does NOT have the $4AFB0001 header then the QL does nothing with it? i.e. no initialisation code gets run etc. And therefore any program that wants to make use of whatever it has in it, HAS to call routines in it directly pleas...

Re: QSTAR 1
Really nice game, Andrei, and nicely polished presentation! I did know it as a demo program ("D-Star") for the ZX Spectrum that is part if the SDCC C Compiler, but yours has much nicer animation, fonts and color. Couldn't find much of a flaw in it except maybe that the animation delay you ...
