Still hoping someone does Marble Madness on the 7800.... or... 7800 Crystal Castles, which was actually an early launch title but never materialized... If we are going to have all these new capabilities, the 7800 needs new games (but enhancements to existing one will definitely be welcomed!) Oh... 7800 Vanguard ?

In truth, we all suck a little because we really don't have enough free time... and already a lot of fantastic (and secrets) projects in WIP / dormant status... Otherwise, with your 1MB board + XM, we would already think of something like that... 9 Link to comment Share on other sites More sharing options...

Hopefully they'll ship soon... will have my gloves and N95 mask ready when they arrive for complete spray down with disinfectant (Not kidding!) Demineralized water right after to wash away any chemicals from disinfectant too! Great to see the boards are finally completed. 2 Link to comment Share on other sites More sharing options...

Besides, unless they arrive <72 hours after they are shrink wrapped, your risk is essentially zero anyway. Viruses generally don’t live long without a host to replicate in. EDIT: saw another study that suggests a week. So Lysol then iso bath. 5 Link to comment Share on other sites More sharing options...

RevEng Posted February 16, 2020 Share Posted February 16, 2020 One more idea to kill any potential coronavirus surfaces - heat them to at least 56°C for over 15 minutes. That info is for the SARs coronavirus variant in a cultured medium, but it's likely to translate to the current COVID-19 strain as well. In this case the survival medium wouldn't be as ideal as the lab tests, though with an unknown starting load of virus, I'd still zap the suckers a bit longer and/or hotter. Easy enough to do if you have a temp-controlled reflow oven. Or any temp controlled oven, provided a significant other won't shoot you for sticking potentially contaminated stuff in it. Starting with heat treatment would minimize your potential exposure to the virus, since you'd only handle the boards minimally. 2 Link to comment Share on other sites More sharing options...

I'm actually pretty impressed with the games so far I've played on the 7800. Since I have a bare board with no case, I definitely want to do the A/V mod on that one, then come up with something for a case... Looking forward to getting my own XM! 1 Link to comment Share on other sites More sharing options...

Synthpopalooza Posted February 17, 2020 Share Posted February 17, 2020 So some questions still ... 1. Does the YM2151 include a 9th channel for samples? some arcade games that use this chip have a sample channel 2. Would doing a A/V mod on the 7800 allow the XM POKEY and YM2151 sound to come through?

If the mod is done correctly so that it combines the audio in line from the cartridge port, it should. So basically, if you do the mod such that you can hear audio from Ballblazer, Commando or any of the modern POKEY homebrews (or Rikki & Vicki!) you should hear XM audio. 1 Link to comment Share on other sites More sharing options...

Another example is Atari System 1 games such as Indiana Jones and the Temple of Doom, as well as Road Runner. They contain the TMS5220 or TMS5220C chip for sample support. Gauntlet (II) and Star Wars also utilize the aforementioned chips, along with ~30 other Arcade titles. 2 Link to comment Share on other sites More sharing options...
Synthpopalooza Posted February 17, 2020 Share Posted February 17, 2020 (edited) OK, I altered the zanac theme ... The open hi hat and tom toms have been removed. We have 8 voices, and each of the 8 channels has it's own voice, in sequence. This way we're not changing voice data in the middle of the song and eating the CPU in the process. It also increases the chance of the module being converted into a format that can play on the XM. RevEng ... do your stuff. make us an .A78 out of this ... zanac-8 voice.wav zanac-8 voice.dmf Edited February 17, 2020 by Synthpopalooza 4 Link to comment Share on other sites More sharing options...
RevEng Posted February 17, 2020 Share Posted February 17, 2020 Thanks! Working on it, for sure. I spent a good chunk of the weekend coding up a parser for DFM files, and it's at the point where it can print out all of the song info, instrument data, the pattern matrix, and the pattern note data, all in human readable format. The program still needs work though, because the DFM data layout is structured for deflemask to easily load it's stuff, and to match internal structures. e.g. empty bits of the song are comprised of a lot of contiguous short rest notes that eat up space. I need to massage the program to output the data in structures that make sense for a 6502 driver, in addition to culling unused patterns and other stuff that won't be used. Then I actually need to write the 6502 driver that uses that data and sends it to the YM. But the good news is, the format is decoded, and there are no longer any big unknown issues that might stop me. It's just a matter of putting in the time. 6 Link to comment Share on other sites More sharing options...
YANDMAN Posted February 17, 2020 Share Posted February 17, 2020 For some unknown reason i awoke this morning thinking ..wondering about the XM. I was going to make a post asking if there was any update? ....and here we are. Pretty darn awesome. if there is anything else anyone wants me to think about to manifest let me know. 1 Link to comment Share on other sites More sharing options...
