Master System 3 Collection 120 Super Jogos
Post Posted: Tue Feb 20, 2024 8:08 pm
Hi all,

I got this console from Révo in hope to extract the following previously undumped games:
A Ponte
Air Hockey
Anaconda
Aniversário
Asa Delta
Batalha Naval
Bil Bolha
Blocos Mágicos
Caça Palavras
Canhão
Corrida da Pesada
Corrida de Tampinhas
Encanamento
Faroeste
Força Alienígena
Guerra dos Monstros
Lance Livre
Mexe Mexe Tupi
Mosaico
Natação
Pedreiro Polar
Zôo

A lot has been discovered about this hardware and to his disappointment all those games are in fact Megadrive ROMs not Master System ones.

There are only 3 chips on the motherboard:
- TECTOY-580 (QFP138)= Megadrive on a chip, yes it's actually a MD not a SMS
- 16MB (128Mb) 16 bit flash (TSOP48) with a similar pinout than a MX29L3211 with two repurposed pins to extend addressable size: pin 12 (GND) becomes A21 and pin 36 (!WR) is A22
- Altera EPM3064A CPLD (TQFP100) for the games decoding logic. I populated the missing JTAG port and to my surprise it wasn't even locked (file in attachment)

What's interesting:
- populating the missing SMS cart slot allows to boot physical SMS carts
- replacing the first 4MB of the flash by a MD ROM does boot the game

To be completed...
EPM3064A (3.0).zip (5 KB)
CPLD

That's a cool find congrats! I wonder if they ever thought about releasing a Master-Mega console at some point.

Probably MegaDrive users wouldn't care that much about SMS games?
I don't know, but it didn't in fact happen.

Sure, I was waiting for the green light from Révo and got it now.
But even zipped it's too big to be attached here...

Here it is… it’s apparently implemented as one giant Mega Drive game rather than separate ROMs.
MS3_120_in_1.zip (10.07 MB)

Some games have small changes from other releases, like the copyright year,or instructions.

Hi, I didn't think this was worth making a thread, but in case anyone is searching about this console or another version that uses the same chip, it's possible to make it sound better and mod it for RGB. Akino_R11NOR wrote a tutorial on his Twitter, I can't post a link because it's one of my first posts.

As Twitter is somewhat impossible to use now and will likely not be a stable source, you could copy/paste it here.

Good idea, the pinout is:
R; Pin 9
G; Pin 10
B; Pin 11
C-Sync; Pin 13
He didn't mention which pin has the mono audio, but that's easy to figure out, and of course since it's an RGB mod it needs a board with a THS7316 or something similar. Interestingly he also used the second internal cartridge slot to wire a Mega Drive cartridge port.

This doesn't surprise me since I'd imagine a lot of the SMS-specific chips were out of production at the time and TecToy was churning out GOACs by the bucketload. Interesting that all the games were crammed into a single ROM file though.

Not that it affects the console a lot, there is a list here that has less than 30 incompatible games for the Mega Drive with an adapter, plus all of the games that rely on the TMS9918 modes, like SG-1000 and Coleco games. Still, if they wanted to have more authentic hardware they could have asked Majesco, which was manufacturing the Game Gear all the way until 2002, it would have been interesting to have a GG in a Master System shell. If Akino finds a way to install the 3D glasses adapter I'll post here the how to.

It seems like some people have already tried, but even by restoring the missing components the slot won't work.

This guy said he used the 112 version as a comparison and even then it didn't work.

It might be a case of whatever BIOS is there isn't programmed to detect the cart slot.

Hey there, I've just got a Master System 74 Super Jogos from a street market. From what I've seen it uses the same TECTOY-580.

Until now all the games I've tested using a flash cart works.

Let me know if you guys want me to do any test on it.

you can run the SMS Test Suite and confirms that the VDP is detected as a Genesis/MegaDrive one - it should be

I've done the test, here are the results:

Hardware tests
JPN?: No
VDP?: 315-5313
TV?: 60Hz (NTSC)
MediaEnable?: No
Z80 type?: CMOS

Model: Genesis/MegaDrive
Region: USA/BRA TV:60Hz (NTSC)

Is there any way I could boot a Mega Drive game on it? LoL
I've tried but I only get a black screen.

According to Apocalypse (first post of this very same topic) if you change the contents of the internal Flash with an MD game, it will run (the menu you see when you boot the console with no cartridge inserted is an MD ROM). Of course you would have to restore the original contents to get back to the standard functionality.

My work:
Post Posted: Sun Aug 11, 2024 10:18 pm
Good night everyone. I've learned a lot about the console in the last few days, and yes, it's a megadrive. I've already played some games on it, and I post my video attached. I raised a lot of pins. And I believe there are different versions of the cards. I discovered a lot with mine. I'm very busy right now and I need to deliver other work. But as soon as possible I will post everything I discovered. I believe I have discovered the logic behind CPLD. I think I can now swap out the original internal games, as well as make a reproduction cartridge with the internal games (with working menu), but I still need to test this. As for CPLD, I'm sure there are different firmware versions for it. Check out my quick video where I run SOR on it. Keep an eye out, as soon as I have more time I will post the results of my work online. It took me a while to do these tests because my plates took a long time to arrive from the post office.

Good night everyone.
New updates follow. Here I show (in Portuguese) the preliminary pinout of the TECTOY580 chip (ATT6001), and the connections I made to run the first mega drive games. I have done a lot of studies so far. We also have the RGB pinout (I know it's already known here). Anyone interested in this (it's not a great discovery, after all it's a megadrive chip running in master system mode, on a master system board). Just watch the video (documents in the description). In the future I may try to connect this to a Sega CD... but I'm too lazy.

That pinout helps a lot, thank you. I have been following your work for a while but I wasn't active this last month. I like the idea of making a custom PCB and just transfer the ASIC, with a few minor changes this could be used for other Mega Drive on a chip clones like SM-801 and TCT-6803 which are still manufactured nowadays.

thank you very much. I have already discovered that what activates the SLOT function is not in the CPLD. Because the CPLD for consoles with 105... 112 and 120 games has the same code. What changes is the memory code that contains the games. (in addition to the extra components on the board). I also discovered that there are different versions of cards for these consoles. I have like 3 different ones now. I have already done the BKP of the CPLDs file for all of them, I will upload them in the future. I'm writing some test codes for CPLDs. And I'm designing a board to make a console with all these versions on the same board.

I did BKP for the CPLDs on my boards too. And they work, I've already recorded and deleted the files several times in tests I've been doing. when I return the original file, they work again. However, my files are POF. How did you get this different file? Can it be edited in any way? It looks like you have some readable words inside your file. Thanks.

Editing: I also noticed that in the header of your file, it shows the name of another component, different from the EPM3064A.
You also mention that installing the cartridge SLOT allows you to run physical games, but in two cases that we tested (motherboard version 4.0P3), this does not work. (we may be using different model boards?)... Even if you add the diodes and other missing components, it still doesn't work. The CPLD of these cards contains the same files as the versions where SLOT works (as I mentioned in the previous post), which shows that the difference is in the MASK memory.

Hi clopes! I´m trying to enable the cartridge slot in my Master System Collection 3 120 games without changing the CPLD. Thanks for the pinout for the Tectoy-580. This will help me a lot on troubleshooting it. The /M3 signal you can use to switch between Mega Drive mode to Master System mode. If the /M3 is floating, it will run as Mega Drive. It you ground this signal, it will run the Master System Mode. In theory, I think that in the Master System Collection the CPLD force the /M3 to ground and run in Master System mode, then it works like a Master System and the bios is in the flash memory. They removed the bios from the Flash memory (Master System Collection 120), so it will not check the offsets $7ff0, $3ff0, $1ff0 for the ASCII text "TMR SEGA"

I have found in this forum a great project about a Multicart for SG-1000, Mark III .... and I will try do replace the internal flash memory with this 16MB raspberry pico with custom came collection. Another test will be install a 27c010 with the EU/US 1.3 Bios following your pinout and see if the cartridge will be functional.

Good afternoon.
I'm not sure if the CPLD or the FLASH contain a BIOS.
In my tests I manually configured the M3 pin to see if it worked, but it didn't (at least on mine, we may have different board revisions).
I believe it must not contain the BIOS, since some games that require STACK didn't work (from what I remember that was it, I need to test again).
In addition to the M3 pin, the CPLD also puts the memory in 8-bit mode through the /BYTE pin. I had to redirect some pins as well (through the CPLD) to complete the entire mode conversion.

I'm glad we're talking about this, since I just built an MD/SMS converter based on Arduino that contains the STACK initialization. So I'll be able to do new tests. I'll get back to you with the answer.

I have just tested the console with 112 games (which already has a functional SLOT from the factory).
The games: THE SECRET OF SHINOBI and MORTAL KOMBAT 1
did not work.
I think these consoles do not have a BIOS.
Or they have some other incompatibility with these games.

interesting findings....

I´m still travelling but when I come back I will make further tests.
I was searching the web, and found a russian forum with some insteresting information about the TCT6001, that seems similar to ATT6001 = Tectoy-580. It does not have RGB on their pinout, but S-video. The other thing that I have found, it that the PSG pin goes nowhere in our Master System Collection, maybe that is why it sounds strange. So, I also found a schematic to solve this issue in the same forum. I would rather use NE5532, because LM358 is a bit "noisy", and this schematic can be simplified.
So I will try these findings on mine, also install the possibilty to 3D glasses. I´m developing a board that goes to the cartridge slot based on the schematics that we have in this forum, but I decided to use dip ICs instead of SMD as it is easier to find dip ICS here in Brazil.

Great discoveries. In some clones, the ATT6001 does not have RGB connections on the board, but they are on the chip (according to some Russian forums).
There are some versions of them with COB chips, and in this case they do not have the connections.
There is a version of these Tectoy multi-game SMS that uses a larger chip, I need to see if it is the same one that was shown.
I remember seeing the sound correction on some Russian forum, but I had forgotten. I think it was here:

I was comparing your pinout and their pinout and it seems that we can follow their signal order based on your pinout. For example the /MRES is on pin 116 but on yours in on 119, so the next would be GND (PIN 120) MOL (PIN 121) and MOR(PIN 122). PIN 36, 37, 38, 39 would be O/J , TV_N/P, TV_ 50/60 - TECTOY580. If Someone want change from PAL-M to NTSC replacing the Crystal.

For example the /MRES is on pin 116 but on yours in on 119, so the next would be GND (PIN 120) MOL (PIN 121) and MOR(PIN 122). PIN 36, 37, 38, 39 would be O/J , TV_N/P, TV_ 50/60 - TECTOY580. If Someone want change from PAL-M to NTSC replacing the Crystal.

Is it the same chip? TCT6001 is quite different from ATT6001. I got my pins in general by tracing on the assembled board. I still need to add some. Thanks for the contributions.
