If anyone still cares, the 64MB compressed ROM based on the previous one is here. 7zip shaved off an additonal 1.8MB or so, 700KB of which was padding (since I like round powers of two on roms and all that). byuu I don't know if you wanted it with or without the gamearts intro, just let me know and ...

If there's any need to video editing, I'm not the one to be doing it! Compression support went no where, the original plan fell flat because after actually studying the bsnes source it does not advance any sort of internal pointer when reading between writes to 420B or whatever. Atleast, it seems to...

I wonder how much this device would cost if it ever reaches the production stage, do you already have an idea of it? I don't know much about the overheads involved but a ballpark figure would be cool, if you have the design already thought out. On a side note, I just realised the compressor tries al...

Thanks for that, I'll let byuu be the judge of quality plus my internet blows at the moment. Yeah ios::binary fixed that up, I haven't had to deal with the sort of stuff since I was making shitty C apps with fopen. It works great now, with the extended compression with uint32 and all. I did quick te...

edit: yeah I mixed up the videos, it was the Saturn MPEG one. I'm having some difficulty with andreas' compressor program, atleast it appears to be outputting inconsistent results for me. I modified the source files with the main routine to take a command line parameter and that's about it. http://i...

Is anyone here good enough with video editing to turn one of those into something tolerable when played at 20hz? edit: for the time being, I am using the DivX video. It definitely has alot less artefacts than the mov one and is a bit smoother. I had to use dithering in irfan view because otherwise t...

I'll work in the compression soon. the DivX one has much better quality, there's so much less artefacting although it stutters just the same. I made it drop frames to fit the 30hz->20hz conversion (in my batch converter not the SNES code) but it is just as fluid as the mov. It stutters in media play...

I worded the thing about tilemaps badly, I do send them at reset and not at any other time. $F600+ is where they sit and yscroll gets alternated. haha I'd put artefacted anime videos way above any youtube poop =). I think DKC series used the 16 palettes and 4bpp tiles to get its very colourful overw...

The IV41 bullshit is resolved, though I had to use an old XP machine to get irfanview to do a BMP extraction. VLC crashed, although I know where to go if I need more IV41 vids dumped. The mov is 15FPS though, you sure you want that? I didn't realise it sucked that bad until I saw I needed to throttl...

I had no clue about the pre-existing compressor, I grabbed mingw and it worked great. I compressed a random ASCII file and tried the following: PHP REP #$10 SEP #$20 LDX #$F000 ;last chunk of ram STX $2181 LDA #$01 STA $2183 LDA #$01 ;enable the chip itself STA $4800 LDA #$08 ;one reg no inc STA $43...

splitting this up because I don't want to add to an already huge post. new rom to demonstrate the 32khz stereo idea. Got the cycle counts right, also destroyed snes9x compatibility, awesome. thank god for bsnes or I'd have nothing to test my screwy roms on. Unfortunately, it needs S-DD1 again. The i...

cool, didn't expect this much discussion for this forum. @byuu: Mode 3 would've been way easier to implement than what I showed in the TMNT demo, I just didn't like the savage ROM requirements since I wanted something to show that I could present with the resources currently available. The 256MB S-D...

@tokumaru: yeah a cartoon is a good idea, i just shuffled a bunch of things around and double buffer in the mode7 tilemap. Since the NES TMNT demo featured the song and I always liked that one, I did the intro video. 30FPS, with increased resolution I liked how it turned out. Might've looked better ...

@tokumaru: yeah I can do requests, they're easy enough to throw together. Aslong as I can open the video properly in virtual dub (since adobe flash gave me hell with anything but flv files) then it's all good. Ofcourse if the source video is 30FPS or something then almost double the length is possib...

video roms

I was recently messing around with trying to get the SNES to display smooth video, I had to make huge comprimises but I got a clip of me playing F-Zero at full speed running here . Process was PJ64->fraps->vdub->irfanview->a program I made to convert / interleave pixels->incbin in xkas. Random stats...
