I've no idea why (just switch off for now) I don't have much time this week so I'm attaching the latest version of the file.

I was able to get them to all come up and work in my DevOS modified unit since it plays PAL stuff, but my actual daily driver NTSC only console just gives me the random bars or black screen after the encryption check.

Eagle Posted April 12, 2021 Author Share Posted April 12, 2021 @-^CrossBow^- try to change byte 57 in file header from 1 (pal) to 0 (ntsc) and theoretically should work All files have signature.

Just either a solid grey screen when I try and test the 16khz file, I get the grey screen with 2 yellow vertical stripes in the same place each time on the Jester file and just a black screen on the 94khz file. Again they did work on my DevOS modded system as it will play PAL without issue but RF output only on that console. Anyone else test these files on NTSC and have them working yet? My DF cart is also on FW 1.06a if that helps at all. Quote Link to comment Share on other sites More sharing options...

+Muddyfunster Posted October 31, 2021 Share Posted October 31, 2021 Both sound good to me, Squadron seems to have a couple of tempo jitters to my ear but it's not a tune I'm really familier with so could just be me Out of interest, compared to a similar POKEY tune, how much extra space does a YM tune take?

Eagle Posted October 31, 2021 Author Share Posted October 31, 2021 A lot. Simply VGM format it's dump of YM registers. Many of VGM is more than 64kb. But compressed about 3-10kb. So when I finish my VGM player I will try do something like RMT2LZSS Problem with Squadron I have is command 0x61 in VGM format (wait nn samples - one vblank is $372 samples in NTSC). But in Squadron is using sometimes 2 and half vblank so I have to improvise :) I still don't now how much time is wasted for Wait_for_YM_ready. Some other VGM files using commands 0x7n so is even more frustrating. I have some tunes done in PAL from @miker and they sound ok. 1 Quote Link to comment Share on other sites More sharing options...

Eagle Posted October 31, 2021 Author Share Posted October 31, 2021 Bionic Commando - The Forest Quote The internal format has not been ripped, but VGM logs have been made from the sound test in the game, emulated using MAMEUI 64 v1.46. Tracks 0x01-0x10 are music and tracks 0x11-0x3F are sound effects. http://www.vgmpf.com/Wiki/index.php?title=Bionic_Commando_(ARC) It's old VGM format 1.50 and file was 64kb so I cut down to 44kb. I also ignored commands x7n, I don't see (yet) reason for making delay for 1/44100 of second PAL only of course bionic.a78 Quote Link to comment Share on other sites More sharing options...

I published my install for the new BIOS over the weekend although the video has been ready for over 2 months. I also have permission from Bob and RevEng to offer them to my clients, but I've only got about 8 on hand right now until AA starts to offer them.
