Re: Write binary data to TRD from ASM

I now have an asm loader that loads everything except $6000-$7FFF (and updates my progress bar). Loading this block is breaking TR-Dos, so I need to debug to see what's going on. I don't really want to rearchitect the game because the codebase is shared with the non-Pentagon version (and space in u...

And I think S needs to be Sir Fred. Controversial, perhaps, but such a great game.
Noooo! Sabre Wulf! Sabre Wulf!
What's wrong with you people, S is clearly Starquake.

Re: Write binary data to TRD from ASM

I've made a little progress. The error returned in $5D0F was 1 No file . i wasn't padding my filename with spaces in the file descriptor. Now I get error 12 The channel is not open in $5D0F. But I have already been using TR-DOS - the code this is running from is loaded from basic with a TR-Dos call...

Re: Write binary data to TRD from ASM

Hi Hikaru , I wonder if you could link me to your copy of 'ZX-Spectrum & TR-DOS Для пользователей и программистов', if you have it as a scan. The one I have only goes up to page 114. It's either a different book or it's missing all the good stuff :) Heys. This is the scanned version that I'm using....

Re: Woot! ZXMAS Tape Magazine 2017

Certainly, I will have to disagree with this being a bad year for the Speccy. I would also say sprawling epics are very much in demand! Dat Santos ending though. Loved the Doodlebug too. Bob's puzzlers have some interesting ideas. Unfortunately I think '12 days' has a bug. If you cancel a link just ...

Re: Write binary data to TRD from ASM

out of interest, what is the best rom to use for testing (compatibility wise?) Well, the original 5.03 is considered the baseline version of sorts. This is the last known official release. Another widespread edition is the unofficial 5.04T, which comes as the default ROM in some major 'Pentagon'-or...

Re: TRD boot loader

Yes, it's probably less relevant in the case of boot.B, the only difference I can think of is when it is loaded with LOAD or LOAD "boot". Otherwise, the default implied command for those is RUN. Looking at my own loader, the autostart marker is #80 #AA placed after the final #0D at the end of the BA...

Re: TRD boot loader

It looks like the 'bad' image has the file type set to 'b' as opposed to 'B'. The ASCII code for 'b' is 98, so that should at least explain the 'custom header type #98' thing. Something to do with trdtool perhaps? BASIC files need some spesshul treatment in TR-DOS in order to enable autostart from l...
