Sorry no, but we have guy in Europe very close to you

who can do it, let me contact him and then I will PM you. I will of course pay for shipping.

It would also be good to get the missing MCUs dumped for MAME, some people have already committed...

Missing MCU dumps (M72)

Battle Chopper (World)
Ninja Spirit (World)
Image Fight (World)
Legend of Hero Tonma (World) (AlxUnderBase)
Dragon Breed (M72)
Daiku no Gensan
Air Duel (Japan, M72) (twistedsymphony)
Gallop (Japan, M72)

NOTE:
After the MCU is dumped it can easily be written back to an 8051!

I think I might have the Gallop or maybe I sold it to Mitsu, don’t remember, have to check.

After a bit of back and forth @AlxUnderBase has the Japanese version which is dumped.

Now @MoppelTheWhale can you dump one of your program ROMs and post your checksum here ?

Thank you all for volunteering to get stuff dumped

rtw · Jul 16th 2019, 2:52pm

@MoppelTheWhale dumped his ROM and sadly his is the Japanese version as well.

So if anyone has a Tonma and are wondering if it is the Japanese version please dump
the chip labeled: tom-c-h0 and if the crc32 checksum is: a63204b6

We have a winner

MCU: my donor is dragon breed so I am assuming I have that one? willing to help!

rtw · Jul 18th 2019, 8:46am

@Mrhide, thank you for offering, if you PM me a picture of your PCB or ROMs that will be nice.

Sorry I am a bit late to this.

I can dump the following MCU's (I had Tonma World, but I sold it!) They are all M72 JPN versions

Mr Heli
Ninja Spirit
Dragon Breed
X-Multiply

Would love it if you did an 'alternative' ROM set for the M72 Multi maybe all World revisions (when you get the MCU dumps) and the JPN R-Type 2 (better IMO)

How are you going to dump the MCUs? They are always read protected (otherwise what's the point). Or is there a known method to unlock them (power trick, etc.)?

I've used as many World revisions as possible however the following titles only have a Japanese version on M72:
- Air Duel
- Hammerin Harry
- Dragon Breed
- X-Multiply
Of course the world versions could be ported from M81/M82 to M72.

Japanese R-Type II better? Well it's noticeably harder with more enemies and different patterns.

Obviously you can't read secured i8751 MCUs straight with a standard programmer.But you can do it only after erased the security bit with UV exposure.Team Europe successfully did it many times and also Porchy recently.This is obviously valid only for chip where you can remove the top or the lid and obtain access to the die.See posts below for further details of the process :

team-europe.blogspot.com/2019/…apping-mcu-from-1943.html

jammarcade.net/choplifter-mcu-dumped/

This is a dangerous process so, for interested people, I don't recommend to try it on MCU's which dump don't exist of.It's better first to do some practice on some samples.

Very interesting reading @caius.

LHantz · Jul 28th 2019, 11:03am

Sorry guys, guess I should do more research! I did not realise that the MCU cannot be read with a programmer.

I also did not realise that there were only JPN versions of certain games on M72. Looking at MAME now, I realise that a lot of World revisions are on M81/82

Always had the JPN version of R-Type2, harder but a better game IMO

Mrhide · Jul 28th 2019, 1:35pm

My dragon ~~spirit~~ Breed is the japanese version which is not in mame ... awaiting some news from rtw to see what the next steps are!

caius · Jul 28th 2019, 1:39pm

Next step is that 'rtw' will ask you to send the chip to Team Europe (or someone else able) and they will read the ROM out of the MCU using the process I have described in my previous post, that's all.

LHantz · Jul 28th 2019, 1:44pm

@Mrhide think you mean Dragon Breed (Dragon Spirit is a Namco Sys1 PCB) Looking at MAME, the ROM set is M81, I presume that is the one on the multi (apologies if you have mentioned this previously @Apocalypse ) Any Dragon Breed off an M72 PCB will be JPN

@LHantz As several people have said, the chip can only be read if you decap it, erase the security bit and then read it.

Luckily after the chip has been read out you can burn the image into a replacement chip and your game will be as good as new.

Is the person you sold the Tonma to a member here ?

LHantz · Jul 29th 2019, 3:48pm

No, he was on UKVAC
