Kyuusaku posted on the neo geo dev wiki a verilog code for the NEO-CTO, the chipset that controls the graphics on the Neo Geo.

This is good news for every Super MVS converter owner.
If the code is worked out to fit on the CPLD chip you could easily flash yours and get rid of the scaling problem.

Here's the link for the wiki:

Here's my request for the NeoFlash team:

This is great news :))

Very cool, I'd love to upgrade my first run Neoteam converter.

Does this mean my Daedalus is about to significantly depreciate? :p :)

Or you can just swap the CPDL chipset for a real one from a junk mvs motherboard :)
It will also work 100%

Nope. You guys are forgetting that you still need to put the work in to make the converter 100% compatible. Scaling was only an issue with some P1s and all SMVSC2s. Don't forget about the other issues.

As for the Neo flash team, are they going to offer the fix for free? They should, at least that will fix ONE of the problems with their converter.

Yeah, I'm serious.

I'm aware the converter only work on a few models and the scaling problems but as far as I know on the systems it work, it only had the scaling problems.

Scaling Issues
Compatibility Issues with newer titles and NGDEV games.
MSX Fix not implemented, in fact Neo Flash team mislead everyone that bought the converter to think MSX would work on their system if they bought the additional PSU which has been proven to not be the fix.

And probably some others.

All those issues are related to graphics, which those 2 methods will fix.


"I was able to get it fixed by fine adjusting the pot on the converter."

Fixing graphics would not address the sound volume issue I consistently experienced on more than one console with KOF 2002. There will always be random issues here and there with this convertor. Just not that reliable of a product.

Thanks, Alec, I'm going to check if this problem exist on mine.

I want to have a flawless converter so I'm fixing everything here with help of a few very experienced people.

Well if someone decides to use it in their project I do expect some compensation since it is the elusive key ingredient to making MVS converters as well as new AES carts and this kind of work is my livelihood. Donations are highly appreciated since nobody would sponsor its release, the offers I received were absolutely pathetic so I had just been sitting on it for two years.

When I get around to it I'll try to fix my V2 SMVSCII, and if it goes smoothly I might offer this service to others, more likely than not I won't.

if its open source then you wont be compensated. there is no one to compensate you. so is this release under what license?

The people to compensate me are the people who use or appreciate my work, how difficult is that?

The design is released under the "do the right thing" license, consider it a gift to the community for educational purposes. I didn't draft a real license because for the most part it's pointless to; licenses will be violated and I don't plan to chase ignorant, exploitative assholes online.

the license you post is problematic to using this.

all i want is something diy so everyone can build one or a group buy for cheap on a convertor. but this vagueness seems to be a problem


please forgive my ignorence. i have no intention of stealing from you. i just want something we the comunity can work on without somewhere down the rtoad being slaped with a long letter head

To using what? The burden of compensation falls on whomever is making carts/converters or wants to support the effort. It's also entirely relative. If someone makes carts/converters at cost, which they won't, I would be happy with a shoutout. If they sell a $400 converter or original AES game, I expect a little more.

And actually such a converter is not a problem, they've been planned by myself and others for a long time, I've just been lazy about production.

im idea im looking for pcbs to be made at about cost and a parts kit. aka something we can deal with. not make a fortune on your hard work. if we use it the community sure a shout out is in store.

Kyuusako put a lot of work on this and I believe every human being understand his point.

As a matter of close speculation, the free converter would cost in parts $40 or so.
If you sell for $60 you have enough margin for profit and for a donation to the man behind your product.
Besides, $60 on the Neo Scene is really cheap and would sell like water. Either way, don't bite the hand that feeds you.
