Users with contribution privileges on the site can add missing games:

We've added all Japanese and PAL consoles to the site too so you can add missing imports as well.

There seems to be a bit of contention on what to add.  And the lists themselves are all over the place in terms of the number of games.  I'll let users decide what to add for now.

I've added "JP MSX" and "PAL MSX" to the site as console options, but there are no games yet.  Anyone with contributor privileges can add games they want to the site:

I've processed all the backend so we will recognize MSX sales once games are added.

Sounds like MSX community is very active and passionate :)

I'll look at both of those links and see what can be added.  Eventually I'd like to have both.  We have a lot more PAL users than Japanese users and MSX isn't very popular in the USA so tie probably goes to PAL.

Sounds good to me.  If I can get a list of Japanese MSX games I'll work on adding them.

Is the console region locked?

Can MSX games play on MSX 2 and MSX 2 games play on MSX?

If someone can send me a game list with as much info as possible like release dates and region etc.  I'll look through it and add the games.

Yep, that is how we will do it.  NTSC MSX games, PAL MSX games, Japanese MSX games.

If someone can provide a spreadsheet with the MSX game list I can work to add these.  Please limit the list to NTSC releases for now.  We can add Euro and Japan releases down the line.

You can email the list to sales@vgpc.com

You can do that on the site now:

There is a link on the home page to do the search (right below the console list).  And you can get to the list by clicking on the publisher name on any game page too.

I've added the PAL version.

I don't see any record of an NTSC physical release though.
