The developer said:
Cave are world famous for their manic shooters (弾幕 danmaku, aka "bullet hell").
I have been experimenting with Cave's newest hardware platform, based on a currently unemulated Hitachi SH-3 CPU (having written cave.c for their older 68000 based system, some ten years ago).
The game in question is Ibara, a gorgeous shooter that bears more than a similarity to Raizing's Battle Garegga and Battle Bakraid. In fact they were all programmed by Shinobu Yagawa (his Recca, on the NES, being the grandfather of them all).
WIP screen shots of Ibara (2005) are below, but first...
Important:
This WIP driver has not been submitted to MAME dev (or anyone else, for that matter).
It is not for inclusion in MAME for the foreseeable future.
It won't be for at least 3 years after Cave stops earning from this hardware platform and games.
Considering Xbox 360 ports are coming out in 2010, you're not going to see this game emulated before 2016 (probably later).
Add 1 year for each request I get to release it .
Also note:
The game runs dog slow anyway (peaks at 5% on my Athlon64 3000).
There is no sound (unemulated YMZ770C-F chip, also sound ROMs are not dumped).
No EEPROM/Real Time Clock support (unemulated RTC 9701 chip).
the SH-3 CPU emulation is very preliminary, hacked on top of the SH-4 core.
The graphics chip is an FPGA, programmed at boot by the main CPU. It does high-color graphics blitting with support for several blending modes. The current implementation is probably reasonable, but some details are to be improved. I think colors are a bit off in shadows, for instance, although that may be caused by the low resolution I use to perform the mixing (5 bits). Graphics are stored in 128 MB of flash memory - the chips you can find in USB pen drives or in SSDs - and are loaded in RAM on demand (see the funky loading screen).
For more infos on the hardware and games see World-of-Arcades and System 16.
Thanks to Guru.

Luca, tieniti la tua emulazione e non rompere i maroni, visto che non vuoi includere il codice nel MAME. Il tuo lavoro attuale è INUTILE.
