If this could be tested on a CDZ or whatever is available that would be great. I'm actually expecting this to fail because I did not patch checksum code at all, if it exists here like it does on AES/MVS it will be a problem. It did not come up in emulation so I am blind to it at the moment. Will be fixed if it is encountered (exact wording of the error message will help in locating it). If it flat out does not work at all, specific info on what happens leading to crash will help. There are a bunch of things to iron out so I have a few ideas if it doesn't work.
Just making sure, this is the CD player you get on your system,right?
Also, wondering what would happen if this were run on a top loader..If the stock CDZ BIOS works on top loader, I don't see why this wouldn't.

For extra RAM in empty sockets, a test program can attempt to write to areas that were previously empty and see what happens when trying to read it back. Not sure how the hardware is set up for taking extra RAM though.
Also, some more ROMs for you NTM, it might help if I uploaded sets at a time to test a few different things.
-neocdregular is the same thing as before but ironed out a bit with a few changes, if it still resets, try the below ones.
-neoregdump should display a few numbers on screen. If this doesn't work, I have to pick apart the boot process.
-neonocnt has disabled input, removes a few variables from the problem
thanks. Aslong as NeoTurfMasta wants to test ROMs I'll be willing to get this thing going.
Yesterday I fully populated my CDZ with the compatible ram. First I was having some graphical issues, but they went away after I found some loose pins. So whenever you want to try that too. I have enough ram to upgrade 7 more CDZs if this works out. There are 12 empty slots for these chips.
Any chance you have a doc on the soft dip layout? If not, I'll just figure it out on some MVS game in MAME. I just want a simple menu that lets you adjust those settings and optionally save them to the NVRAM. I think developers wouldn't consider stripping soft dip out of the CD releases, wouldn't make any sense.
From what I remember the Neo CD toploader has a backup ram section on the main board.
Edit: Here's an old pic I took:
Kunio said:If it's possible to populate the empty ram slots in a CDZ, wouldn't it be possible to create working CD convertions that go beyond the original 56 Mbit, putting the new limit at whatever we can achieve with more RAM?
Also, doesn't the CDZ have some sort of extra memory that helps with some of the short loads?
