King of Fighters NeoWave

I've successfully converted also King of Fighters NeoWave!!

Unfortunately, has the same problem as Metal Slug 6 and shows black screen on real Naomi but works great on MAME.

Hopefully the problem/protection that is causing this is the same in both games, and even with more luck the same one that is causing the games not to works on Naomi 2.

With the Naomi Development kit I could do a lot more and faster....if someone heard from someone where it could be downloaded please PM at the neogeo forum.

Stay tuned for more.

METAL SLUG 6

I have successfully converted METAL SLUG 6 which works great on MAME but shows black screen on Real Naomi. I will start finding out why and release it ASAP.

I have also found that the first Atommiswave games had almost or no protection. The conversion process was "quite simple". The problem I'm facing now and that's the reason for lower pace in releases is that I found out that the new games have LOTS of protections inserted in the code in order to avoid games from AW being ported to DC or Naomi.

To give one example:

In memory region 0x10000-20000, Atomiswave has a flash rom and Naomi a ROM, so the AW game will try to erase part of that flash rom, everytime we boot (which btw decreases the life of our flash) and write some values there. Then it will read back from that part of memory. If we read the same, then we are good, if it doesn't read the same because Naomi has a ROM there, then it will crash or go to endless loop.
Another trick is to try to send weird commands to the GDROM, which AW doesn't have. You follow me right? In a Naomi will make the whole DMA, PIO pointers go crazy but will be ignored by AW.
Another one is to try to write to the extra ram that the Naomi has. If we read back the same, then we have extra memory that shouldn't be there and it will crash.

To put in short, Sammy, Sega and SNK probably faced a problem of piracy and started putting anti-copy measures quite sofisticated. Conversion of games from AW to Naomi is already quite a challenge, but that it's now clear to me, problem are all those anti-copying/anti-porting measures.

Just in Metal Slug 6 I had to modify the code in 47 places!!!

Hopefully I'll release something very soon!

I converted FOTNS and consider it fully working. This game is really good and the music is just awesome. This game is one of the reasons why I decided to convert AW games to Naomi!

This game is converted and works great in MAME but not in the real Naomi. I'm trying to find out why. Probably some Video mode setting issue. Any help from Dreamcast programmers would be welcome.

Update and Clarification (UPDATE 1)

This week I'll send the two CPS3 ISOS (custom and SH2) to all the donors that wanted to have the CPS3 CD.

When I get their feedback then I feel comfortable to order printing the final CDs. This should happen in two weeks.

Following with Atomiswave to Naomi Project, I've seen a lot of misinformation and wrong assumptions that I'll try to clarify. I'm working on converting all the games, this is the final goal of this proejct, even the racing and shoting ones.

I'm going to release the games publicly in bundles of 3-4 games as soon as I can. Games will be release when 10 donations of over $20 have been achieved. Please notice that the meter on the right is manually updated. It's not automatic. If you donated €40/$50 then you'll get a DVD with all games and design by Alex once all the games have been converted.

I will release however the games as soon as they are ready to the donnors so they can test it in advance and to thank them for their support. If they want to have the DVD earlier I can send it to them, but I think it makes little sense if it's not ready.

Hope this clarifies everything.


* UPDATE 1: I have sent Dolphin Blue and Rumble Fish for Naomi to the donors.
* UPDATE 2: I have sent Final (hopefully) ISOS of CPS3 for standard and custom sh2. If you have donated or have reported at least 1 bug (which means you are interested on this and are not a rom collector) and you haven't received the email with the links, let me know. I won't print the CDs until I get general approval.

Next Game Rumble Fish

I have 99% ready Rumble Fish, however given the little number of both donations and feedback, I've decided to set a donation meter on the right. When it reaches 10 donations, I'll release Rumble Fish. After that Dolphin Blue will follow again after 10 donations. Next game??? You can make suggestions on this entry or vote in the poll on the right.

I know some people will not be happy about this as they want to have everything for free, they give no feedback and ask "Why it's taking you so long to fix this?", so that's the approach I've decided to go.

Nothing else changes, I plan to release all games, only that the pace will be set by the people interested on this.

Releasing Guilty Gear X Ver. 1.5

You can find in the link below the file for Guilty Gear X Ver. 1.5 for Naomi.

Please report if you find any bug.

Donations are VERY low, so if you enjoyed this consider donating towards the DVD. Sorry guys to insist, but it's very frustating to get little reports and little donations, looks like no one is interested.
