was this ever solved? is it the white button or trigger or both which activates the slowdown? because the mad catz blaster has the white and black buttons on the side
No I don't think it was. It seems people lost interest on trying to get Chihiro going on xbox for now which is a shame. Let's hope it picks up again at some stage
Hi, I am currently developing a modchip that interfaces on the LPC port. Thread here I was wondering if there would be some benefits to try and add "BASIC" spoofing of a MediaBoard in the modchip's code. When I say basic it's because I really don't have much ressources left in the cpld to do moderately complex logic processing. Right now, cpld could reply 0x00 on the whole 0x4*** address range which would at least spoof a FPGA rev MediaBoard ID and supply other locations with 0x00 instead of the 0xFF you'd normally receive when no one answers at those adresses. Anyway just asking but I read that JayFoxRun did some marvelous work with its Chihiro-Launcher. Maybe he already included some sort of spoof for this via software.
So I will be adding MediaBoard version spoof to FPGA version and 1024MB DIMM size detected. These are the 2 checks made by Chihiro BIOS on the LPC bus to identify a MediaBoard connected and detected on the BUS.
I have no idea. Maybe some Chihiro XBEs do check for those parameters... At least it will not hurt if you try to boot using the chihiro BIOS. The BIOS do check for those but I do not know how much it will help to make Chihiro games work. Frankly I wouldn't put any hope in this!
What would be interesting would be a modified Chihiro BIOS. Your modchip should make development of that a bit easier but yes, even partial emulation of the media board would be useful. I have one I can send you if you needed to study it, it has several flash roms on it which may prove handy. Probably not the place to ask this but as it's an FPGA could a separate firmware not be written to it so it could be used only as a media board emulator? Does it have spare I/O? BTW some games (like OR2SP) check for presence of the network board also. This is a separate board that attaches to the media board but still goes through the LPC I believe.
As it goes, seems all the flash dumps are already in MAME: Source: http://mamedev.org/source/src/mame/drivers/chihiro.c.html How MAME handles things should be noted as they have OR2 running much better these days (albeit about 2% speed).
Sorry for the triple post but those tools miss an important step, creating the extracted PIC data. You need to put the pic file in the same directory as extract-securityic.exe and use command line (or a batch file) like this (using Outrun 2 SP PIC file for example): extract-securityic 317-0xxx-com.pic 317-0xxx-com.data This creates the pic file the wizard is looking for. Using the MAME one straight up will not work. *EDIT* I hope no one minds but I added the necessary steps to WizApp so now you can just select the MAME pic file rather than having to extract it first: https://www.sendspace.com/file/xk1471 I had it leave the file after the process finishes too as it's handy to have for future reference. *EDIT2* Looks like some pic files are already extracted in MAME (OR2 for example) so this won't work for those, I might add a selector to indicate if it's extracted or not if WizApp supports it.
Thanks for your contributions. I can load any bios with a special phoenix bios loader on my dev kit, if it can help for test. I try with chihiro bios from mamedev but freeze on black screen I already say that but Crediar succes to run some of triforce games on WII, with his quadforec, I think he solve some of problem about board emulation.
Yeah it would freeze as the media board needs to be present. I'd imagine your box would also frag (if it even gets that far). It'd need the bios modifying but even then, half the bios is in the media/JVS board. Quadforce is interesting as though the triforce and chihiro are totally different systems, the media/network board etc is very similar.
media and network is the same with triforce, the flash too. I have a I/O JVS board sega type 2, but the is not usb signal this rj something, I would try to connect it with my crystal dev kit via usb but I think does not work.
Yes it's not USB, it's RS485. IIRC you could damage it by plugging it into USB. A baseboard would need to be present in the xbox board and it'd plug into that. If that modchip above could be used as a baseboard emulator that would be able to be plugged into it. It would still need modification though as the MCPX would be different (in a retail box). More on that here: http://hackspot.net/XboxBlog/?p=1 Hacking the XBE is probably still the best way to get these games running, which is a shame because it probably means JVS would be impossible (inputs, lamp and FFB outputs etc).
I don't think I handled the LPC writes because there is no way to set I/O breakpoints for the entire range. So at best you can hook 4 I/O addresses iirc. Having it in the modchip would probably help to check if it improves anything. If it does I might be willing to add it to the launcher. I'm busy writing my bachelor thesis (About virtual FATX Filesystems in QEMU) at the moment and also work on xqemu which will hopefully support Chihiro at some point. I documented FATX some more for the thesis and extract-fatx will probably be updated to reflect some of my new findings. Also, about MAME. I believe they also only have OR2 Beta running - not the final. But it's been some time since I have checked, so I might be wrong.
I'm not renewing my webhosting so the Chihiro on XBOX wiki will be going away at the end of this year. If anybody wants to host it let me know, it's easy to move.
looks like its a dokuiki installation so it'll be tiny (the actual page data anyway) if codeasm doesnt want to host it i will
It is dokuwiki - the entire folder is only 34MB. Move info here: https://www.dokuwiki.org/faq:servermove Really, the only useful information is the game test page which could be incorporated into another site.
I just noticed an off-by-one bug in extract-fatx which is also in xbox-linux (and most other FATX tools probably). That might have even corrupted files during extraction which might cause crashes with some games. I will probably fix it mid december.
