I have some news about that came from our own current beta testers regarding the older version of 16K Venture compressed. For one thing, the game does not always crash, even after that sound crackle is heard. The game keeps playing. It also a random glitch that does not happen and crash all the time. One reason why it may crash is parts of the program are now deflated into RAM instead of majority of it on the cartridge ROM. Anything loaded into RAM can be altered. If something is going on with RMT pointers reading memory locations not a song and it starts writing to random locations in RAM where the program is running from, anything can happen. Several different versions of RMT might had been used for different version of Venture also.
Now this sound problem does not seems not to be occurring every version on different OS, hardware configurations, and video hardware. It is not happening with the 400,800, 600XL, 1200XL. Also does not happen with the AltirraOS XL/XE OS. However we do not support glitches in my games generated from conflicts with OS hacks, custom hardware, or anything running an emulator. However Post# 424 should have information hacking a fix.
It is not too hard to figure out why this got missed back when we first made Venture to run from a 16K cartridge so we can sell it for $39.95 instead of $49.95. I probably was focused on making sure it still runs on the 400/800 or had Altirra set to use the Altirra XL/XE OS. I usually leave the Firmware to the default settings for my first tests, I did not look into how to set up all the OS configurations until a year ago. Several different versions of Altirra had been put up for download since 2014. The Venture ROM image was sent to Video 61 and given to Kjmann so they can do the real hardware tests.
I had the 16K version ported over back in March 2014, Kjmann was still running things and did not want to release it until the Portland Retro Gaming Expo in October. He has several Atari computers, and I believe we was selling 600XLs configured to 64K, Stereo Pokey, and Super Video upgrade. I have no information which machines he beta tested Venture on. Anyone can ask him which hardware he tested it on. This sound glitch was not known and reported to us until this year, 3 years after the game had been released.
We have an updated version of the game that will be released going forward. Anyone who has issues with the game, does need to sent me a private message or email or call Video61.
