Games Hidden Inside Arcade Machines | Nostalgia Nerd

All those glorious arcade games to play, yet, how did they get there? Who maintained them? How did this world of wonder actually work? Well, behind the scenes there was a lot going on, made easier by JAMMA cabinets. JAMMA arcade machines came with their quirks though, including secret games that we never actually got to play.

How was a cabinet without a PCB considered to be an "unfinished electronic product" and therefore "unsellable", but the PCB (lacking the cabinet, power supply, controls, screen, etc., needed to make it a complete and functioning game) was not? Having to include the Mini Vaders PCB simply increased the cost of the cabinet to comply with the regulatory requirement with absolutely no benefit to the consumer (either the buyer of the cabinet or the customers who actually played on it).

I've played some of these while browsing through MAME ROMs! That stripped down Space Invaders maps s lot more sense now.

I had it on the MEMOTECH MTX512 as COSMIC RAIDERS and I have seen the machine code which was very interesting unfortunately the unit went kapoot as the CPU and GPU overheated and burnt out.(sorry for shouting)

@ 13:30 – Looks like they turned "Tank Battalion" into the tank board in "Tron" a few years later. Of course "Battalion" was probably originally inspired by the Atari 2600 game, "Combat," which I think had its own arcade-based predecessor in the early-mid 70's… 🧐

Daley Thompsons Decathlon was the first spectrum game to use a hyper loader iirc. dead quick loading.

Would like to see a credit to Sharopolis. I think it's pretty unlikely you haven't seen his video on the same subject.

I'm surprised that Z80 chips were apparently so readily available as late as the early 90s.

If they’re trying to ship empty cabinets and have to include a board so it’s not unfinished electronics, how did the actual game boards get shipped? They’re incomplete on their own too right?
