The title of this game translates from Japanese as 'Twin Bee Yahhoo! - Uproar In A Mysterious Land'.

The J-Pop song played in attract mode (make sure that get it via the dipswitches) is called 'Bokura no Suteki' and is sung by Mariko Kouda. Here are the Japanese lyrics :

kanashimi no mori o, sama you kimi wa -

futo sora o mite, uchuu o omou -

ikutsumono ginga -

IMEEJI shita, sono mune ni -

umareru yuuki -

yume o mite, aruki daseru no wa -

bokura no SUTEKI sa, kimi to -

mirai e yukou -

soba ni ite, sasae au koto wa -

inochi no SUTEKI no hitotsu -

kodoku ni ochinaide.

Here is the translated version :

You are wandering about the sorrowful woods -

See the sudden skies, think about outer space -

A lot of Galaxies -

On that imagined chest -

The courage to be born -

See the dreams and we can begin to walk -

You are lovely to us -

Going to the future -

It's in the side and supports each other -

The one lovely life -

Don't fall alone.

- 30th March 2003: R. Belmont enabled the shadows in Konami System GX driver and tilemap alpha blending in the Mystic Warriors driver. David Haywood fixed flickering sprites in Metamorphic Force, graphics layer offsets in several games in both the Mystic Warriors and Konami System GX drivers. Acho A. Tang added the infrastructure support for 3 independent colored shadows/highlights as required by the Konami games, and he cracked the protection in Violent Storm.

The sound is fully emulated but there are some graphics problems in the 3 games that are working (Gokujou Parodius, Twinbee Yahoo! and Sexy Parodius) and the rest of the games suffer from unemulated protection.
