Used "Champion Roadrunner" cartridge for MSX, with case. However, this is a junk item. I confirmed the game's startup recently when I sold my MSX unit, but it didn't boot. I didn't try any troubleshooting such as cleaning the contact points, so it might work if cleaned. Please understand that this is a junk item. There's a 1000 yen sticker on the case, but this is from a time when MSX software was sold cheaply a long time ago. It wasn't originally treated as a non-booting item like this. Thank you.
