RedThunder Posted February 3, 2017 Share Posted February 3, 2017 (edited) Hi All, I've been playing John Anderson's Rally Speedway and want to create my own tracks. I've created the a new track but I can save it Has anyone managed to to create a Trax Disk in Altirra that works. I keep getting reported "Disk Error" :-( I'm using the RS ATR from: http://ftp.pigwa.net/stuff/collections/holmes%20cd/Holmes%201/ATR%20Games/Games%20M-Z/Rally%20Speedway.atr Is there some sort of procedure to make this work in Altirra. Or am I just being plain dumb Best regards. RT PS Altirra amazing bit of software and has brought back so many fond memories of my yoof in 1983.

+MrFish Posted February 3, 2017 Share Posted February 3, 2017 Disks are set to "read-only" by default in Altirra. 2 Quote Link to comment Share on other sites More sharing options...
RedThunder Posted February 3, 2017 Author Share Posted February 3, 2017 I've tried changing to R/W and it worked once. I saw the track list 1-18. Tried booting again and Disk Error :-( I've created a disk call rs_trax.atr and keep trying to write to that by swapping the disk in file and changing to R/W. I'ts got to be me doing something wrong.

Roydea6 Posted February 3, 2017 Share Posted February 3, 2017 Is the ATR locked or protected in some way. If byte 16 in the atr header is 1 it is locked --- if byte 16 is 0 then ATR is not locked. 1 Quote Link to comment Share on other sites More sharing options...

If byte 16 in the atr header is 1 it is locked --- if byte 16 is 0 then ATR is not locked. I'm not quite sure what you mean ? But I'll try and have a look. The disk (atr) I think I've created for tracks is attached. Track 1 & 2 some track tiles deleted. rs_trax.atr Quote Link to comment Share on other sites More sharing options...
Roydea6 Posted February 3, 2017 Share Posted February 3, 2017 That ATR is blank with just the header bytes. It needs to be initialized or formatted before use. 1 Quote Link to comment Share on other sites More sharing options...
RedThunder Posted February 3, 2017 Author Share Posted February 3, 2017 I'll have another go. Quote Link to comment Share on other sites More sharing options...
RedThunder Posted February 3, 2017 Author Share Posted February 3, 2017 Got it working :-) I was not saving the disk when I left Altirra. The disk was created within Rally Speedway Track 1, 2, 3... now load with a few trees missing just to check if it worked. Now off to create some custom tracks I never did in 83 Thanks for the help guys. ATR attached. rs_trax.atr 3 Quote Link to comment Share on other sites More sharing options...
carlsson Posted February 6, 2017 Share Posted February 6, 2017 Is there any documentation on the data format? I noticed the Atari version supports 18 tracks per disk and the C64 version supports 24 tracks. Given that each track seems to consist of 32x25 elements and direction pointers, where each element is one of 31 possible shapes, it seems to be a very verbose or sparse format. Also both formats appear to save the tracks to fixed disk blocks/sectors rather than DOS compatible files. While that shouldn't complicate it too much for anyone looking to make an external track editor, one would have to go through the disk blocks to find out which are used and for what.
