I'm tracing out the Tomy Break Up game now; that will probably fill in some gaps. That radio service manual had the MS pin tied high, but Break Up has it tied low.

I started on a Mitsubishi MELPS 4 microcontroller family emulation core. Known games using it are AFAIK:
- Coleco Frogger
- Gakken Frogger (or is this the same rom as coleco version?)
- Gakken Amidar
- Gakken Jungler

Rik: do you know any other games using this MCU?

Also, this thing has an output-PLA similar to TMS1x series. I've read about someone(nickname: blanka) that decapped a Frogger MCU. Is the die picture online somewhere? And if so: more than just the ROM.

I uploaded the Tomy Break Up info: www.seanriddle.com/tms1040.html

And a blurry video to help with timing: www.seanriddle.com/tomybreakup.MOV

My bad- they both have it tied to positive voltage, which on the game is labeled GND.

Gakken and Coleco Frogger are different. Probably not by much, but the VFD is slightly different, and it's a different ROM code.

I'm not sure (off the top of my head) if any other games use that MCU or not... I'm sure we'll find at least 1 or 2 more...

I sent an Email to Blanka to see if he has a pic of the Frogger die handy... I'll also look around and see if I saved the chip from a dead Frogger I scavenged for parts. Not sure if I kept it or not...

I guess those traces that have been drilled out are for testing that the PCB was made correctly? I see that all the time.


Here's a 58 MP GIMP XCF of the Sears Auto Race die; there are 2 layers- one with and one without the top metal layer: www.seanriddle.com/searsautorace.xcf

corrections:
tomybreakupraw.bin: change offset $034: $CD to $DF
entexbasketball2raw.bin: change offset $713: $7F to $3F
football4: looks ok

Do you have a pcb photo of Football 4? I'd like to know the LEDs positions. If the game ever turns on green+red, it could mean either a 2-colored icon, or orange.

Sean by the way, with all the MAME license updating, I have to officially ask you if you're ok with the license in the source files I credited you in. smile

I tagged them as BSD3. More specifically, lemme just copy-paste it directly:
// license:BSD-3-Clause
// copyright-holders:hap, Sean Riddle, Kevin Horton

Thanks for the corrections. I updated my files.

The LEDs are surface mounted, with the green and red ones only about 1 mm apart, behind opaque plastic. So I bet if both LEDs were on, the colors would mix. Here's a pic:

It's interesting that there is an unused row at the 50 yard line.

The BSD-3-Clause license is fine, thanks!

Here's what he has:
http://www.handheldmuseum.com/Z_Imgs/MESS/froggerchip.zip

A couple of shots of different parts of the chip with an inexpensive microscope... I don't think he has the chip anymore, so we'd have to sacrifice another one to get better pics... But maybe this covers what you need (assuming they are clear enough)?
