    icon16.gif Something I've been working on.

    Back in the spring I worked hard with mikew on something for the Neo Geo CD system. I have had a break on it for the last couple of months but will be working again on it soon.

    Here is a video which is basically a proof of concept. I'm not really going to delve too much into what the end result is going to be but maybe this will take your minds off some of the other happenings in the forum.

    Yes, the PC is uploading the game from via USB on the pc side to the joystick port on the neogeo cd side. Andro Dunos is a game that can fit onto the CD system without level loading required. Just to make it clear this is the MVS version of the game.

    Super cool. So, the PC is required for this to work? Is the PC just "there" serving the files and the BIOS in the CD system does the work?

    Would it be possible to program the BIOS so all games are compatible? Every title requires custom programming right? The fact that that is the MVS version of AD is the most interesting thing...

    Only compatible with game that dump fully on the NGCD RAM? Could RAM be expanded?

    Transfer rate is the same as from CD to RAM - that bottleneck still there?

    Wonderful work and I have a million questions, so I will stop.

    Thank you,

    Awesome! All this cool stuff is happening right after I get a Neo Geo CD. I can't wait to see where this goes. When you're ready to sell these, I'm down for one.

    Oh and pretty much everything Cohaagen said.

    Out of curiosity, would it be possible to use the compression algorithm on CDs themselves. (I.E. Have compressed data on the disk that a special bios could read?)

    Some games already do that. (That's what OBJ files are). Its implemented very poorly though and that said it would not be very fast because it would not be done on the fly.

    Here is a new ISO that I need testing on all types of CD systems. When run it will return a single Word value. Pressing A will run the test again, hopefully the number will be the same so it will look like nothing happened. Pressing C should exit the test. You can get it from http://unibios.free.fr/cd-cdz-test2.zip

    For the above I need to know the value, if its always the same and what system you got it on.

    I also have a second request if anyone can help. I need to make some space in the bios and to that end I want to down sample the power on jingle sound. The current size of that data is 128k, decompressed to wav its 513k. I would like to half the same rate if possible making the sound only 64k if its possible. There is also a second tone sound at the end of the data but that can stay as is. If anyone can help here I have uploaded the data with a decompressor to wav to http://unibios.free.fr/pcm.zip. Is this something that can be done by altering the PCM only or will the z80 program code also need changing?

    I have been having a play with some ideas for a new radio screen. This is knocked up in paintshop and not on NeoGeo hardware but it gives some idea of what I would like to change.

    That's a neat idea Raz, maybe you could offer a service for custom bg image insertion to an ordered bios???

    You're ghostin' us, motherf***er.
    I don't care who you are back in the world.
    You give our position one more time,
    I'll bleed you, real quiet, and leave you here.
    Got that?
