[Vectrex BASIC playtesting... OMG, OMG!]

Hi, long time Vectrex owner (got mine at CGE early 2000's) new to this board. Count me in as an interested user/tester for VexOS! What a great idea.

[[WATARA] [VECTREX] Flash cart rewritable multigame cartridge available]

I'm very interested in purchasing this. I'm looking to get Animaction working on my vectrex (i have a light pen) and was wondering if anyone knows if it would be compatible with this flash cart? I heard the original cart had extra RAM or something built in; would that affect functionality with this?
