jindroush Posted June 5, 2021 Share Posted June 5, 2021 Hi, as mentioned in this thread: are there verified cas dumps somewhere which have: a) loaders with countdown counters b) very long blocks and few IRG pauses - I remember Fort Apocalypse having that Somehow I'd like to "hear" them again. In fact, CAS would be best, but simple video would help too. Quote Link to comment Share on other sites More sharing options...
+CharlieChaplin Posted June 5, 2021 Share Posted June 5, 2021 Something like this ? (CAS = full version, MP3 = cut after one minute) Dimension_X_CAS.zip DIMX_cut_MP3.zip Uses (mostly) long blocks (approx. 2048 Bytes per block). There is also a nice Aackosoft version of BC's Quest for Tires, after the loader it has one long block 16k in size (the whole 16k game = 1 block).

Wrathchild Posted June 5, 2021 Share Posted June 5, 2021 If I recall right, didn't the Mercenary tape have large blocks? Quote Link to comment Share on other sites More sharing options...

manterola Posted June 6, 2021 Share Posted June 6, 2021 I have copied some "weird" .CAS into this tnfs server: fujinet.us.to Quote Link to comment Share on other sites More sharing options...
Rybags Posted June 6, 2021 Share Posted June 6, 2021 News to me - although I did a short loader + 8K block (at higher bitrate) of the AsmEd cart that would load in about half the time, I had no idea that commercial games ever bothered to use such a technique. At the least, it's a really good copy protection method since there's no easy way to know what length is being used if it's not the default (and additional to that you could probably use a different timing sequence method which would make SIO based copying next to impossible) Quote Link to comment Share on other sites More sharing options...

And it actually works in Altirra. Great (will look at its guts later, just for fun). Quote Link to comment Share on other sites More sharing options...
jindroush Posted June 6, 2021 Author Share Posted June 6, 2021 I also downloaded Fort Apocalypse from fujinet.us.to (goddamit, the only way I found out is tnfs_client.py but it works only from Linux), and althought it is not the one I had in mind, it's very funny - playing music and Pong while loading is amusing.

jindroush Posted June 6, 2021 Author Share Posted June 6, 2021 Hi Paul, pfff, mere 17 years of time spent in interrupt and people start to ask questions! It's just some people around here are trying to salvage some old stuff and I currently have some time to play with such a stuff. Just virtually, no Atari hw in my house anymore (or, again).

Did we not used Stereo double tape for dubbing ??? Edited June 6, 2021 by Heaven/TQA 1 Quote Link to comment Share on other sites More sharing options...
