G-NET Emulation in MAME

The new chd format isn't a problem. You can run "chdman -update" and it will fix the old chds so you don't have to download them again.

Thanks. I think I'll see how much extra data the torrent reports I'll need to re-download - it's less wear and tear on the disc to update the regular ROMs with a merge update, for instance. But I wouldn't be surprised if this update asks to do every download over again, so I'll probably need to look into that.

I sent along the estimated amount of cash needed to buy the equipment (along with a note about how excited I was for GNet emulation), which I guess either didn't work (never found out, but considering it took six years...) or the money was simply used for something else (likely!).

In 2003 the donations were handled by Randy, however they was eventually
moved over to Guru. If Randy did not pass your donation info along you
would not be listed on Guru's page. If you contact Guru with the pertinent
information I'm sure he will add you to the list.

Just to emphasize, money donated via Guru's page is only
used to buy dumping equipment, fund the decap project and acquire
boards for dumping.

Good to hear all this coming through. Looks like Night Raid isn't working yet, but it'll be nice to play with less input lag

is xii stag working yet?

null1024 · Post by **null1024** » Sat Mar 21, 2009 2:05 am

Has anyone here tested it yet? And does Raycrisis work? MAWS is being useless on the status [and any info] on the G-Net sets...

Sure, XII Stag is working. I've tried it and Psyvariar Medium Unit, Shanghai, and Chaos Heat (awesomesauce indeed).

CH seems pretty close to the actual G-Card/PCB version. There is no music and the stage select screen in Psyvariar has a bit of graphic corruption- but the G-Net driver is great for just having been released, and it runs fine (60 FPS on my Dell XPS 210). Nice job, Haze & OG.

Chaos Heat rocks the casbah. It actually kinda strikes me as a spiritual successor to Taito's Lightbringer, lots of similarities despite the drastic setting and mechanics difference.

Score tip of Macaw! Once most types of enemies die they release a 'core' (the small red parasite things). Each one destroyed gives you the value of the previous one plus 10 points, so the value for destroying them just keeps and keeps accumulating. Time to milk enemies!?

weird that these are all listed as working when then is clearly no music present ?

Post by **nZero** » Sun Mar 22, 2009 6:44 pm

The games boot, you can play them, ergo: working. Sound CPU and DSP are as of yet unemulated (same as Taito FX-1B board)

The soundtrack on CH is hot stuff- a tad reminiscent of the BGM from XIII on PS2/Xbox.

Milking a few enemies here and there doesn't sound too bad of an idea.

You may be blowing off your time bonus, but you raise the "core" bonus at the end of the stage.

Oddly, Zoku Otenami Haiken DOES have music. A good thing about the G-Net emulation over the real PCB- you can switch games and not have to reinitialize. If you just swapped games on the actual PCB, you'll be waiting 2-5 mins - even if you've played that G-Card before on your motherboard.

Yeah, the sound is 50% emulated at best. No music, and repeating sound effects that get stuck makes it not really playable in my opinion. Still a nice attempt so far, so kudos to those mame devs involved.

I do wonder if this means I could burn a PCMCIA card with the CHD to play a couple games I do not yet have on my GNET?

Also to bad they had a problem dumping Zooo...one of the best games in my gnet collection.

Have you found a PCMCIA card big enough to load the files on? I've looked before and they all seem to be tiny, and expensive, and old.

Edit: Nevermind, the files don't take up much space after all. Odd for a polygon game.

The latest gnet cards (like zooo) are actually CF card based PCMCIA adapters. Although you need the latest GNET bios upgrade to play them.

Is Shikigami no Shiro playable?
Cool!

I know they had to write custom software to dump the data off the cards so I'm going to venture a guess that just dumping the data to a card with 'normal' tools won't result in success.

Also if it were that easy you'd see more boots

Ed Oscuro · Post by **Ed Oscuro** » Sun Mar 22, 2009 11:26 pm

welp, played through Chaos Heat and cleared 61% (hooray no name entry, I had an extra credit in). I'm sure it'd be tough as nails to go through properly; I just fed credits.

In retrospect, I'm happy I didn't buy this one when I had the chance - small playfields and one joystick, although each character plays very differently from the others (the ninja-looking guy seems to be the easiest; I played all the way through as him). It's okay, but sort of exhausting.

MAME emulation needs better than a Core 2 Duo E6600 / 2.4 GHz to run fullspeed all the time. It was playable though.

Ah, you are right, in fact thats exactly what guru says on the g-net page. Probably for the best to avoid bootlegs.

I love Dungeon Magic/Lightbringer and don't know Chaos Heat nearly as well, so unfortunately I don't see the similarities. Enlighten me please! Are there lots of secrets in this game I don't know about?

I don't milk enemies btw (I go as fast as I can), but that's something to look into when I try this in MAME.

G.net emulation > My PC. Can't get any decent framerate. Let's hope someone makes a ZINC-like emulator for it. I'm sure it would be way faster than MAME.

Ed Oscuro · Post by **Ed Oscuro** » Mon Mar 23, 2009 6:57 am

Chaos Heat has these action sequences where you gotta do something or else you get sent to a different branching path. For example, there's a spot where I found myself navigating a sewer. The walkway breaks and you find yourself in the soup, dodging incoming barrels. I actually made it to the end but didn't touch the green pad (exit) in time (didn't see it) and immediately got swept away. Instead of dying, the game dumps you downstream. An interesting way to treat the branching paths idea.

Psyvariar, Chaos Heat and Ray Crisis all running pretty nicely with me. Sweet. Best MAME update in ages. Is the XII Stag chd widely available yet? I haven't seen that one anywhere (I'm not asking for links, just wondering....).

i found them all via google and obscure forums in the dark corners of the interweb

They're all as widely available as something uploaded to a well-traffic'ed binary newsgroup can be.

Try inserting the name of the chd into your favourite search engine.

I are be dumb.
[Yay, Psyvariar time!]

edit:
JESUS CHRIST, 30% with a frameskip of 8?! [and with 9-12]
Dear God, that's depressing. I know my machine's crap, but most 3D games in MAME [read: ZN based hardware/STV] run at 50-90% on my machine... I'm not even going to try RayCrisis [especially since I have the PS1 version]...

One in the second stage is where a DEF agent will try to unlock a door for you, and you must guard him for 30 seconds as these spider things come into the room. Since you're about to clear the stage from here, whether he lives or dies determines which of the two bosses you face.

null1024, what is your machine? Just curious if you're getting this kind of speed with a lot of frameskip.

I'd hate to see what NAOMI games would be like in MAME (200 MHz SH4, and way higher PPS 3D than G-Net). For them I'd probably use NullDC or Makaron.

Yes.

Torrents are a lot easier than google for stuff like this. Both places I checked had them all. I know a couple of sites where you can direct download chd's actually, but they're not as up-to-date and there's no point really.

I failed.
