There's three 74HC139s, which are dual 2-to-4 line decoders.

This maybe is used for wiring up one of the expansion ports to the ISA bus?

A YAC512-M. This is a DAC used by the OPL3 to create the analog output of the audio chip.

A PAM8403 three-watt class-D stereo audio amplifier.

Assorted power regulation/charging circuitry that I'm not going to go into.

though I do want to show off this amazing bodge job.

So the keyboard PCB is also the display converter PCB. It stars a Realtek RTD2660, which is a standard video controller. It takes in analog video and drives LVDS displays with it. It's an all-in-one chip that's used on a bunch of cheap monitors, and it's also an 8051!

Next to it we've got a P25Q40H half-megabyte serial flash chip. This is presumably used to store configuration info for the RTD2660.

The other chip on the keyboard/video board is an HM82C42. I can't find any info on this specific version, but it's almost certainly an Intel MCS-48 acting as a PS/2 keyboard controller.

The keyboard is a rubber membrane onto the PCB, like a remote control. It's functional but feels pretty crap.

that large connector on the side is called "ISA" on the PCB.

The other connector is 12 pins:
This one is PS/2 and VGA. An adapter is included with the device.

there's also the SBVGM audio player, which includes "Funky Stars" and the whole soundtrack of PlanetX3

@forelioned @dosnostalgic I heard about it. It's a scam but sadly I don't have the money to find out exactly what kind of scam it is at the moment

@dosnostalgic merry Christmas!

PSA

I extracted the password-screen animations from Lemmings 3D. Turns out that's super-easy, they're just in one big raw file and every frame is 32x32.

Ruin a DOS game by adding a word:

Titus Andronicus the Fox
Cosmo Kramer's Cosmic Adventure
David Duke Nukem
Police... No, too easy.
Kilowattblaster
Fallout Boy
Heroes of Might and Stage Magic
Double Jeopardy
Sid Meier's De Colonization
Theme Park Hospital
The Incredible Fucking Machine
Day of Tentacle Hentai
Rise of the Triple Triad
The Big Dig
Chicken Wing Commander
Shadow Puppet Warrior
Blood Donation
Stairway Descent
Gabriel Knight: Sins Of The Step Fathers
Spousal Abuse

I'm also interested in ones that aren't in the top few. Like, once you have Commander Keens, Dukes Nukems, and Jazz Jackrabbits, what's next?

What are the best DOS sidesrollers, in your opinion?
