The One Chip MSX will be configured as a special MSX1 computer by default, offering 256kB of RAM, MSX-MUSIC, MSX-DOS2 and FAT16 support

1chipMSX was MSX 2 by default. I bought one in September 2007 from Japan.

Yes, it has VDP issues, some very important, but is a MSX2 by default.

Neo Lite doesn't include Joystick controller. It is just for Limited version.
(Joystick is too heavy to ship. It is steel. )

@spl: have these VDP issues been resolved by now?

@vanfanel: no, not entirely...

The th9958 is a mod of v9938 model: HRA has left the project in 2008!
His vdp have the MSX2+ functions but also new bug versus v9938 that the same HRA has introduced...

On the next v3.2 will be removed some of these bug
(this is an hobby for me I do not have much time to implement all the deficiencies of ocm).

However this project is still open, it seems to me a good thing!!
I hope be satisfied with the little that I do.

@KdL,
Good luck to you Smile and thanks for good work.

This Zemmix Neo project is also a hobby for me but it became much bigger than my thinking for now..
Anyways I want to make everyone satisfied though Smile

@KdL: In the past I recall reading from you that v9938 core (MSX2) is more compatible with MSX1 and MSX2 than the experimental v9958 (MSX2+) we're using on the OCM and Altera DE1. If I'm right, how difficult would be to have separate MSX2 (more compatible) and MSX2+ (experimental) relases?

Or has the v9938 the same compatibility with MSX1 and MSX2 software that the v9958 experimental version?

And another suggestion: Did you know about this OPEN and FREE Master System implementation, including VDP?
https://github.com/ben0109/Papilio-Master-System

It uses the T80 CPU also (and older version). It has been ported to the Minimig V1.1 board, too. Take a look here to see how far it has gone:

Maybe it could be incorporated to the current core and we could get a super-special Master System compatible 1ChipMSX :D

@mygodess: thanks a lot!

@vanfanel: th9958 and v9938 are the same but HRA have introduced bugs, my goal is to implement an all-in-one vdp without bugs; the Master System will be good idea to get PlaySoniq inside of OCM but is not a priority. Thanks for links to source code, very useful.
