The truth about Atomiswave to Naomi Project

I have heard some rumours that arcademodbios.com (AMB) says that he is the one converting the games and that this is all his work. THIS IS FALSE!

AMB converted the first games, that means the games that had NO PROTECTION, ZERO PROTECTION, LITLLE COMPLEXITY. When he noticed that newer games had lots of protections and were more complex then he didn't like the project so much, but the real reason why he left the project is another one.


To start with, I agreed with him on helping him on the project to make sure it will become a reality. We discussed how to publish the converted games and get some reward for it. We decided to go for donation mode.
I wanted to make sure this project will become a reality and here is shocking news, I agreed on giving him ALL the donations that we achived. All for him. Zero for me. Even with that when he saw that the level of donations was not the one he expected, well, he just quitted and let me alone with this. How do you like it? Obviously he won't get a cent.

It is true that when we started this project, AMB had already done some code that will read the game content from DIMM instead of AW cartridge and will translate JVS Input to Maple Input. The trasnfer routine uses some lame PIO mode that is quite slow and is the reason why some games still lag.
These parts of code were created by him and I'll be using them until I have succesfully converted all games, so I can concentrate on the conversions itself and avoid introducing new bugs. This will be replaced by real DMA transfers, once I finished converting the games as this code is not the best and I had problems with it as it changes too many registers which are later on used.

I have spent hundreds of hours (literally) in this project and  removed a lot of protections related to HW differences between AW and Naomi like:
* Checking for the Content of the BIOS
* Use the BIOS code for calculations.
* Flashing areas of memory that in Naomi aren't there and checking if they are really flashed.
* Trying to read from the programm code again, once the program has been loaded into RAM
* Etc.

The worst of all is that I forwarded him all the contacts of people who wanted to get their CPS 3 BIOS updated with MY Cps3 BIOS (maybe now it's also his Bios :) and when people complained that they don't have the latest ISO, you know what he did, he said he couldn't help and he forwarded them to me!

If he has done all conversions already, I challenge him first of all to prove it and second to release here and before the end of the year Metal Slug 6, KOFNW, KOF XI and all the driving games. I know he won't do it, because it won't bring him any money.

Happy 2014!

Driving Games on Atomiswave

I bewlieve I have some issues with  my Sega I/O and can't test driving games properly. If someone has a driving NAOMI cabinet and would like to test some conversions, please let me know!!

The King Of Fighters XI

This game is 99% completed now. I just gave it a try on the real Naomi and....what do you think? The same black screen hang just as the beggining when initializing video. Brrrrr.

* Green= Converted. May have some issues.
* Blue= Looks like can be converted.
* Red= Not working on MAME. Much harder to convert. In worst case will need to wait until MAME supports it.


Notice that converting the games is something that is already under control and this is not what is delaying new releases. Problem comes from the many protections that producers have inserted into the code, to avoid ports or bootlegs, so each game must be converted + fixed. Each protection can take up to 30 hours to fix!

Games from 2003 and some of 2004, have little or no protection, so they are much easier to port. After that companies started using multiple protections to try to stop bootlegers or conversions.
I've seen many tricks, like trying to write to the memory with typical ERASE commands. This has no effect on a Mask rom, but is the precise command to erase a Flash rom. You follow me, right.
Games also check using some complicated algorithms doing calculations with the values present in memory area 0x0-0xFFFF. If the AW BIOS isn't there, game won't boot. Solution is to copy at least part of the BIOS into Upper Naomi memory.

More  updates soon.

Sega Clay Challenge

I succesfully converted also this game (except analog) and again it works great on MAME and DEMUL, but doesn't even boot on the real thing.....this is making me angry now...

Link here for the ones who wanna try it.

Sega Bass Fishing Challenge

I succesfully converted Sega Bass Fishing Challenge (except analog controls) to Naomi and it works well in MAME and DEMUL (In noami mode) but as happens with MSLUG 6 and KOFNW it won't boot on the real thing....This is now pissing me off! It seems to be the same problem in all 3 games. Probably video related...

I guess I'll need to take care of that as 1st priority now.

Guilty Gear ISUKA. Converted!!

Guilty Gear was succesfully converted and will be released today to donors. Please give your feedback on how it works for you.
