I tried out this file for the English version of Puyo Puyo Fever and am getting a black screen also. Any ideas?

My Set-up:
Naomi2
Multi-Bios set to USA [fixed version]
Capcom I/O [or JVS I/O]
NetDimm 4.02 [512MB]
RaspberryPi PiforceTools

Did anyone ever manage to get Puyo Puyo Fever's English version to work?
I tried it again yesterday and am still getting a black screen when I try to load the English version, but that regular Japanese one works fine.


[Edit: The "puyo_pop_fever-[GDS-0034]" file found elsewhere on the net is the export version that's in English and it will netboot and load without issue.]

Thanks very much @MetalliC - read up on those two topics, and they explained everything I was missing!

For others if they are interested the issues were:

- I was reading the addresses the wrong way around, due to the endianness. When I was quoting 0x00000040 I really meant 0x40000000 and ditto for 0x00003000 I really meant 0x00300000.
- This made it easy to see that it's only the first 0x300000 of the first IC that is actually decrypted, and not the first 0x800000 as I thought. The fact there is an unencrypted header at this point should have been a good hint lol (this unencrypted section is clearly the test mode, that for some reason in this game sits unencrypted unlike the other m4 games I looked at which encrypt test mode as well).
- The 40 I was seeing was actually a flag (explained in the naomi source code linked by MetalliC) to tell the naomi to decrypt that section. Seeing as I decrypted the first sets of bytes myself using a brute forcer, this needs to be turned off so that the naomi loads it as plain text.

Now very happy with a working netbootable version of Manic Panic Ghosts!

Next task is to try and get hold of a real serial IO board for the game so that I can find out the protocol and try to HLE it so I can play the game!

This is good info. :D Sending a PM. hopefully you are willing to share the bin file with someone who can test it on a legit cab :D

I'm having a weird problem with HOTD3 on Chihiro. Its a type 3 netboot setup and everything works except for music. I have sound effects just no music.

Other games work and have music. Its just HOTD3 that does not. I even tested on a second Chihiro unit and had the same problem.

Anyone else experience this or have any suggestions?
 
That patch changes the byte at: 0x2102e from 0 to 1 anyone know what that does ?

edit:
Answering my own question, it's a patch to make a type 1 image work on a type 3 unit

It has to be 512MB, the original GDX-0001 image is only 512MB. There is no reason to use 1GB on the Chihiro.
For some strange reason the Chihiro requires a dedicated image for each memory configuration.
 
is there any benefit to running 1GB over 512? any games require it or worse off with the lower memory?

this was originally a 1GB unit with the sticker and everything. seems strange that Sega would add in an extra stick and not use it.
 
I don't know of any games which require 1GB. IIRC some later games had 2 images stored on the GD-ROM one for 512MB and one for 1GB,
 
Reconfiguring to a 512MB setup is working with music! I played through most of the game with no issues. Thanks!

(for anyone else who needs to do this, switch over JP5 on the media board to position 2-3, also not sure if it matters but I left the stick in that is furthest from the ports)

Hi, can I ask for somebody to make a netboot image for Initial D3 Cycraft or if it exists? I haven't seen that file anywhere.

The game is dumped in mame as inidv3cy.zip - dm me and we can see about converting it, I think there are guides.
I'd be interested in helping if you'd be able to test out my emulator with this game - https://github.com/bobbydilley/cycraft-emulator
Do you have a real cycraft?
 
This is GD-ROM: GDS-0039B.
If you have a CF setup you can run the decrypted binary directly.
