Ok, a few JPN saturn orphans for grabs...
Metal slug manual $5
Radiant Silvergun case and manual - shoot me an offer.
Gekirindan case and manual - $10

Also - I have a ti99 joystick adaptor box up for GRABS.
This will allow you to use ATARI joysticks on the TI99. I built this myself and it's been heavily tested. $10.
