Anyone know a way to get a 128mb Xbox for Virtua Cop 3?

:/ indeed. Doubt I'll ever see this. Not buying a light gun compatible 480p CRT.

 

Ye same here all I want a debug console for is to play VC3. I'm still hoping that blueshogun96 is able to emulate it on cxbx

 

Speaking of that, this is my latest update on Cxbx and Chihiro games: http://shogun3d-cxbx.blogspot.com/2013/03/more-on-chihiro.html

Haven't had much time for it, but I devoted a few hours to it last night.

 

Does anyone recognize these ports?

Not sure what these are...

 

No idea at the moment. I can try to check it next week though, I have lots of port documentation at home (currently at my parents).

If they are only on chihiro games I'd assume it's the baseboard communication.
You don't really need it in the beginning though (might be necessary if games are not cracked?) - I just checked in my own emulator and I ignored all port i/o. I still got to a point where I had the Chihiro logo showing up.

Could you provide a backtrace with detected function names? Also, when does this happen and what happens if you ignore these?

 

I don't believe the functions have names, but I can probably still give you the stack trace.

What I did was add some code in the exception handler to skip over the privileged instructions. These start getting executed somewhere after JvsEEPROM_Write is called and when I ignore them, nothing bad seems to happen. Right now, the game is trying to register an shutdown notification with a DPC. I can easily get passed this, but after that I don't know what's going to happen.

EDIT: Skipped passed the privileged code and added all the necessary JVS functions, and now I'm getting Direct3D initialization stuff. Now I'm just stuck on one function where the stack trace is utterly useless...

 

Okay, finally getting somewhere with this. I'm not making any promises, but it looks like someone's dream might be coming true.

I'm also curious as to if this error message would appear on a retail Xbox with 128mb.

 

I'm glad these is starting to go somewhere and might be the solution for those without a debug consoles to play this game. I know many people will say "hey what about light gun support" but we should take one step at a time. If we get this working is already a major step. We may be even able to run other Chihiro games on it. I will keep my fingers crossed but seems to be heading the route we want right now.

A big thanks and congrats for those using their personal life and time on this. I would also if only I had the know how and patience. I had programming in University but never liked it so much (probably because of some idiot teachers I had but that's another story).

Keep us posted

 

Okay, got the test menu to show. After receiving the parameters from XLaunchNewImage, it started showing this. The garbage on the screen behind the text is just a result of the render target not being set/cleared properly (AFAIK). The menu does work, but will crash upon exit and it's an internal crash that I've never been able to fix because my debugging skills suck.

 

Not to hijack, but: I have a Debug kit I'd sell for the right price if this helps you in your crusade at all. It's patched to run all .xbe's.

 

Thanks, but I already have a debug kit atm.

 

For me, the same thing happens to my xbox (v1.4/Focus 128MB) Anyone knows how to fix it?

It seems that, an additional RAM in this version is useless.

 

It's a hardware problem, nothing you can do.

 

i have a ordinary xbox but got ram/cpu upgrade done by trusty

vcop3 runs fine on it. I use ems topgun 3's to play it but ive played through all 3 levels (although i failed at the end becaue we didnt kill the main boss lol)

I do have to run stupid mameox before i play the game or else it wont run though

 

Oh, so the light gun does work. One of these days, I'll have to get that model so I can stop using the annoying gamepad.

The Ram doesn't speed up your console, it just gives you the memory required to actually fit the resources into the first 128mb of the 4gb address space.

 

Yes the EMS TopGun III works, but in VCOP3 on xbox you need the right trigger to use slow-motion "bullet time", does not take care by the gun. Only A,B,X,Y are availlable on the gun. Need patch to change it.

Other question, do you have any pist to code one patch to launch arcade version, or other Chihiro games? Ram address?

 

You guys read my mind I was coming now to ask if the TopGun III worked on VC3. Got my answers. Pitty about the trigger, did you try to contact EMS maybe they could supply a patch for it since VC3 is probably the only shooting game from xbox with people actually playing it or wanting to play. I'm sure it would help them to sell a few more if they could map the controller in full.

 

I don't think they'd be really interested in adding features for Xbox1. The gun also works for PC and I bet they intended to sell this mostly for PC users. I bet they put in the Xbox1 compatibility simply because it was a direct port of the LCD TopGun II.

But if you never ask you'll never get it, that's for sure. Just don't get your hopes up.

 

I know that, the problem starts when xbox begins to use extra RAM.

 

The solution to my problem the whole time was given here in this topic - MAMEoX128 Plus. Now Kameo (on all maps) Made Man is ultra fast lol
