続・Yabause for PSP

昨日ネタにした「Yabause for PSP」を落としてきて
readmeを読んだんだけど……

Also, please note that Yabause REQUIRES a PSP Slim (PSP-200x) or later.
Yabause isn't (yet?) lean enough to run in 24MB of RAM. Sorry!

ぎゃー！＞＜
PSP-1000ではゲーム起動は無理だってさ！

＃PSP-1000でもCD画面までは行くって。

ついでに使い方も引用しておくか！ 暇だからな！（暇じゃねーけど）

How to use Yabause (PSP-specific notes)
---------------------------------------
There is currently no way to configure Yabause, so copy the data you want
to run into the same directory as EBOOT.PBP with the following filenames:

BIOS.BIN -- BIOS image
CD.ISO -- CD image (can also be a cuesheet)
BACKUP.BIN -- Backup RAM image (optional)

The directional pad and analog stick can both be used to emulate the
Saturn controller's directional pad. Button controls are predefined as
follows:

Start -- Start
A -- Square
B -- Cross
C -- (unassigned)
X -- Triangle
Y -- Circle
Z -- (unassigned)
L -- L
R -- R

なんだ、当たり前だけどボタン足んねーじゃん。(^^;)
