Rik, did you ever check what Colorvision games you own? I recently managed to get a hold of a Colorvision PCB which I can send to Sean if he wants to take a look at dumping it, but I only own 1 game (Submarine) I believe you had all the others except Beasts Planet? Would be nice if we could have these preserved while we still can and considering there is nothing to dump in the actual carts this is one case where scanning/photographing the carts would definitely help.

Yes, I have Horror House, Jungle Boy and Monster Chase. I'll be able to document those cartridges.

Sounds good! Looking at Rik's PCB pics, the power, osc, input and segment locations on the blob are consistent with the Sharp SM510/511.

Well, after several years with Ranger Lannier's R-Zone and carts, I think I've finally done enough for Hap to get a game going: http://www.seanriddle.com/rzone.html

Indy 500 has the same SM510 variant as Space Jam, which uses a resistor for the oscillator instead of a crystal.

There is a patent for R-Zone with a net list, but it doesn't match what I'm seeing. The patent says segment output BS is used for the LED backlight, but the LCD panel uses all 33 segment outputs. It also says K3 is for the button shift register input but it's on K1, and the patent says S1 is for the shift register clock output but I see that on S2 with S1 being the LED backlight control. The weirdest thing is that I'm seeing the shift register /load signal on R2. Usually R1 and R2 are connected to a piezo and are driven opposite of each other for more volume. But there is a transistor on the PCB (as well as a volume control), so I guess R2 wasn't needed and that freed up another segment output.

The LCD panels are a real pain to work with since they are so tiny. And Indy 500 and Jedi Adventure both have a lot of "dead crystals" that show up in reverse color. It's a nuisance to clean those up when they are isolated, but when they cross the border of a segment, it's a lot of work to fix it.

Cool =) I verified the ROM dump, I hope to get emulation working sometime in the next few days.

I took my first pics of a Sharp SM512, from R-Zone's Batman Forever cart: https://seanriddledecap.blogspot.com/2017/09/blog-post.html

A few years ago I (poorly) deglobbed a couple of other R-Zone carts with SM512s (Jedi Adventure and Daytona USA), but didn't know what the die was. Those carts also had smaller dies on the PCB, which look like serial ROMs. I'm not sure why LCD games would need more ROM, though. It would make sense if they had speech, but I don't think they do.

It's interesting that the RAM for the extra 16 LCD segments is completely separate from the original segment RAM.

SM512 doesn't have R2, so I expect the MCU->cartridge connections to be different, probably every output on the S port. SM510 S port is a shift register, SM511/512 S port is latched with an extra opcode (shift register internal only).

Those other 2 R-Zone carts you mention, have extra sound effects.

Bonus mention: Tiger's Super Street Fighter II handheld, pfff

Does SM511 have R2? I always thought that the Pin Connections drawing in the 1990 databook was accidentally a copy of SM510. The rest of the datasheet indicates that SM511 has 1 R output and 2 BS outputs, like SM512. The only differences I see between SM511 and SM512 are C1-C16 added and GND/VDD being moved over a couple of pins. All of the SM511 games I've looked at just use one output for sound and don't use the other one for anything. SM511 die shot looks like the pins are R, BS1, BS2.

I'll have to put a logic analyzer on the connections to the extra ROM chips to see how they are accessed, then clock them myself and capture the output. Hopefully not too many of the carts have extra ROM. I have a few Konami games with speech, but I haven't investigated that at all.

Hmm yeah, it probably doesn't have R2. SM511/512 don't have an ATR opcode so there's no way to control it.

Indy 500 is added and working. Here is the R-Zone driver:
https://github.com/mamedev/mame/blob/master/src/mame/drivers/rzone.cpp

1 interesting thing: The SM510 documentation mentions a mask option for the R port to enable direct control, I added support for that in the SM510 core. Normally it outputs a 4khz tone, every SM510 handheld emulated so far uses that(you can hear a 4khz background whine on every sound effect). The youtube footage of Indy 500 doesn't have that, they must have disabled it. This freed up the R2 pin for direct control.
