CD2193

Undercover Cops SFC was actually intended to be released in late 1993 by irem themselves, without any involvement from Varie (the eventual publisher). You can still find old promo material from irem promoting the game's intended original release. For whatever reason, they shelved the title and it didn't see a retail release until 1995, after Varie picked it up and slapped their name on it, and maybe finished up whatever irem hadn't. Note that no parts on this PCB are dated after 1993.

Happen to save a photo of the cart?

(EDIT: Moving to ebay, but open to offers until I do) For offer. Works fine, just the console. NTSC region, so it plays US and JP NR dev discs. See pictures, and feel free to ask any questions. More pics can be provided as needed. Ships from the USA. https://ibb.co/album/qNTFqH

If I remember correctly (keeping in mind that it has been a few years), that dorwena777 person used to sell Voyeur 2 discs that looked like they'd just printed out the scan of the disc displayed on Hidden Palace and slapped it on the top of the disc, same reflected light pattern as said CD and same white blemishes. Might have even been the same seller who used to always have Mario's Wacky Worlds discs with homemade cover art and the like.

Any other things in particular that you're looking for now? Other Konami stuff in general? Other Contra series illustrations?
