It appears yet another Pikachu5 variant has surfaced... appearing on some other random console ("MGT" Console de jeux), listed in the menu as "Teamboys". It's not really that much of note, I'm just shocked to see there are still even more of these. Going solely by stock images, the entire HUD seems to be removed...
It appears I never posted the TV Baseball ROM here; I did actually figure out how to find it, so I've attached the belated download (alongside a Teamboys picture).
