Uses the MS VDP in compatibility mode, hence slightly off colours.

Maintain the PAUSE button on the console to enter keypad mode: numbers are mapped to the D-pad using the same disposition they have on a Colecovision controller (if you picture it), e.g. up = 2, up + right = 3, etc.
That covers keys 1 to 8 (which is enough for difficulty and player selection in most games).
For the remaining keys: 1 + up = 5, 1 + down + left = *, 1 + down = 0, 1 + down + right = #, 1 + left = F3, 1 + right = F4.

this is very interesting! more details on how it works?

This is mind-blowing! You're on fire.

Never thought my Master System could allow me to collect games for another system without owning the console. Love the idea bc retro consoles break much more easily than retro games, and take space too.

Is there any plans for launching this as a product?
Like your great Mark III to SMS adapter.
Feel free to do an MSX to SMS adapter too if you feel like it ;)

Oh mate, that is awesome!

Same! Initial guess along the lines of - Colecovision has a Z80 and a TMS VDP inside, but presumably different memory & I/O mapping, so somehow you are intercepting bus traffic and conditionally replaying to the SMS hardware where appropriate? If so, presumably only works if the I/O maps don't overlap.

No sound? Is it possible?

If there's enough demand for it I'll make a small batch. But since BIOS is copyrighted I'll need to rewrite the subroutines before I can include them.
I'm also working on a MSX adapter (MSX1 only).

That is exactly what it does, overlapping isn't a problem.
Sound may be a bit low in the video but is present.

Ah sorry, I thought I had my sound turned right up but straining to hear, must be my old age ;)

Out of interest what's the big ol PLCC device we can see there?

It's a CPLD from the ATF150x family, still manufatured by Microchip (formerly Atmel).
Clearly overkill for the job in terms of available I/Os and macrocells but has the huge benefit of being 5V compatible (in 2022!).

Ah nice.

Tell me about it! Finding 5V compatible CPLDs has been a total nightmare for me, they seem to be increasingly rare and with the chip shortage it's so hard to know whether the supply will ever recover, and whether the unit cost will ever be sensible again...

I actually thought for some reason the 1500 series was 3.3v only but I see now it looks like it's only some of them (e.g. ATF1508ASV seems to be only 3.3v...perhaps it's the -V suffix that makes them low voltage?)

Thanks - that's one more on my small list of potentially useful devices!

Yup, it's the V.

(Also, if you read the datasheets for the "V" series parts vs the 5V ones, the current consumption has decreased by 1/3 (i.e. 3.3V/5V) and the speeds have decreased similarly and the absolute maximum rating is the same as the 5V part. I'd be wary of taking a chance on blowing some up, but it's similar enough that I do wonder if there's a real difference)

Actually I recently discovered some of the AS (without the V) chips I had ordered back in 2019 from Mouser and with a datecode from 2018, were actually ASVs...
Too late to make a claim but weird enough to be mentioned, especially them coming from Mouser you can probably rule out some dodgy chinese tactics (remarking).

I'm very interested in these potential future products.

Question, will the adapter work with this?

ColecoVisions Multi Cart. Has anyone tried?

If that cartridge appears as a standard one to the system then yes it should work.

I've been testing a lot of games lately, compatibility is much better than expected!

Games with issues:

Not sure if those games require a specific region (60Hz NTSC vs 50Hz PAL/SECAM), BIOS or controller.
If anyone knows PLMK.

DragonFire (1984) (Imagic) - Works but buggy sprites in upper left corner on MS2. Works fine on MS1 (different VDP).
Final Test Cartridge (19xx) - Works but fails the ROM check (expects an OG BIOS?)
Rock 'N' Bolt (1984) (Telegames) - Small graphic glitches (a few short lines on the moving floor)
Sector Alpha (1983) (Spectravideo) - Lots of graphic glitches in the ground part => game actually shipped broken, see there for a fixed ROM https://forums.atariage.com/topic/224593-sector-alpha-rom-corrupted/

Sector Alpha (1983) (Spectravideo) - Lots of graphic glitches in the ground part
Star Wars - The Arcade Game (1984) (Parker Bros) - Controller 1 does nothing on the wave selection screen, controller 2 allows to move left/right and select wave 1 or 2. No up/down movement.

Sector Alpha is always glitchy, even on a real ColecoVision. It seems the original carts were faulty. Are you using the GoodSets ROM? That one is the real one, dumped straight from a real cart (24kb), which means it's bad. Try using the No-Intro ROM (20kb), which is the one compiled by members of AtariAge that corrects the original ROM's problems.

Thanks a lot mateusbond, I was indeed using the OG and corrupted ROM!
Works fine with the fixed one.

I guess Sector Alpha is just the Cyberpunk 2077 of 1983 :D

Case cover (subject to change).

This is pretty amazing to see this. Even using a 32kB game to see this run is mind blowing.

No up/down movement. Sector Alpha is always glitchy, even on a real ColecoVision. It seems the original carts were faulty. Are you using the GoodSets ROM? That one is the real one, dumped straight from a real cart (24kb), which means it's bad. Try using the No-Intro ROM (20kb), which is the one compiled by members of AtariAge that corrects the original ROM's problems.

Apocalypse Joined: 26 Feb 2021 Posts: 145	Thanks a lot mateusbond, I was indeed using the OG and corrupted ROM! Works fine with the fixed one. I guess Sector Alpha is just the Cyberpunk 2077 of 1983 :D

	Apocalypse wrote Uses the MS VDP in compatibility mode, hence slightly off colours. Maintain the PAUSE button on the console to enter keypad mode: numbers are mapped to the D-pad using the same disposition they have on a Colecovision controller (if you picture it), e.g. up = 2, up + right = 3, etc. That covers keys 1 to 8 (which is enough for difficulty and player selection in most games). For the remaining keys: 1 + up = 5, 1 + down + left = *, 1 + down = 0, 1 + down + right = #, 1 + left = F3, 1 + right = F4. [EDIT]Picture attached[/EDIT] Here's a video of it in action, for now I'm using Colecovision ROMs on a MS cartridge PCB. https://vimeo.com/760660538 This is pretty amazing to see this. Even using a 32kB game to see this run is mind blowing.
