G-NET Emulation in MAME

[Ixmucane2]

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.

I failed.

"...すみません"

Left door it is, then!

I failed so hopelessly that I didn't realize that he can be saved and I assumed the whole segment to be a scripted cut scene (you are left alone etc.) disguised with an interactive scoring opportunity.

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.

My machine?
1.3GHz Pentium M, 512MB RAM, 64MB Intel integrated graphics.
PS: I got it to run a bit faster by totally disabling sound [which is broken anyway] Frameskip is 8 [highest value I could put it at and it'd still look playable].

And for anything NAOMI, I'd have to say hell yes to NullDC [runs Ikaruga on my machine at 75-120% [is Ikaruga supposed to run at 50fps?], MAME would probably run it at 10-20% here.

In NTSC, 50fps would be a tad slow - but that would be right for PAL. Border Down seems to work nicely for me with nullDC. There's a minor graphic glitch in the stage 1 intro, but that's the only problem.

For PS1, I've used ePSXe - I've been so pleased with that one that I never bothered looking for other PS emus. It'd be nice to see ePSXe add support for ZN-1/ZN-2 games, including G-Net.

Hopefully these recent goings-on may cause Zinc to leave its dormant state. My XPS 210 does struggle slightly with MAME Tekken 3 (probably, the full 3D backgrounds are a bit much), but Zinc may do well with that.

The sticking background audio has been a bug common to a lot of PS driver games in MAME (most notably the TGM siren).

That would be awesome if it did, since PS1 RayCrisis runs at a full 60fps in it for me in ePSXe... no glitches or anything...

And for anything NAOMI... MAME would probably run it at 10-20% here.

I didn't think any Naomi based games ran at playable speeds yet. Last time I tried one, it ran at <20% on my computer (2.33 GHz/2GB RAM).

Though progress may be on the way...

Shit, that's twice the spec of my box [4 times for RAM]...
But yay, 3d is implemented [sortof] in MAME for it...

EDIT: Back on topic, XII Stag runs 60-70% compared to Psyvariar's pathetic 40-50% [which makes the game so ridiculously easy -- only time I died was when the bullets blended with the BG]. Sweet.

EDIT2: Back off topic:

Yeah, but I'm running on a NTSC BIOS, and the game is showing up as PAL... was there even a PAL DC release of Ikaruga?

[Wonderbanana]

.. was there even a PAL DC release of Ikaruga?

Nope.

There were actually some derivatives of MAME that tackled that from the other side, i.e. adding support for PS1 plugins. I think they might have just taken the Zinc code, but anyway, you can get one such version here and try out for yourself. MAME++ is dead now though, since some of the baseline MAME devs got angry because it had kaillera, so they forced the author to take it down and stop the builds entirely.

psx is my PS1 emulator of choice, but I really only use it to play 2D games mostly so I might not be the best judge. It seems to run the games I play way way faster than epsxe, while also eliminating the crappy plugin system.

The original PSX is clocked at: 33.8688 MHz.

The G-NET is clocked at: 100.000 Mhz (According to MAME source code)

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!?

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?

- The snake head boss's in the game are incredibly similar to the giant snake boss in scenario 2 of Lightbringer

- Branching paths leading to different areas and bosses

- Soundtrack by Norihiro Furukawa who also did Lightbringer

- The Chaos Heat OST itself has the same design as the Lightbringer one, with tracks interspersed by an english narrator


Thats about it. As for the secrets, I'm sure there are many in the game, I'm still figuring stuff out. Who knows whether it will top Lightbringer in that department though, I remember when I was playing Lightbringer intensely at one point, and there was this bizarre thing that would randomly appear. I think I've seen it twice in about a hundred or so credits of either me playing or watching someone play.

I don't even remember what the 'thing' is exactly its been so long since I last saw it, not even Japanese guides could give me and answer to what that was.

Is area 4-B on Psyvariar Revision supposed to look a bit weird? I wasn't sure if it was glitchy or if that's how it was meant to look.

- Keep Rolling
Roll with holding bomb button when you have no bomb

[ Night Raid ]
- Secret Item
Bring over 6 power-up items into the screen and wait 3 seconds

[ Night Raid ]
- Secret Item
Bring over 6 power-up items into the screen and wait 3 seconds

Isn't this where a whole bunch of tea boxes fill the screen all at once, similar to the end of the levels on Cotton 2 or Cotton Boomerang with them falling from the sky?

If so, this is fairly easy to do at the beginning of the 2nd or 3rd stage, and can be great for points.

Night Raid is easily the best shooter on the system in my opinion. Great music, ground sound effects, and not to mention the special attack is just awesome. The PS1 port of this one kinda sucks IMO.

Seems one new version of MaMe is out.

And now with Shikigami no Shiro.
Cool!
