INTRO
This is an English translation of Steam Heart's for the NEC
PC-98. All of the dialogue has been translated - during the
game, between levels, and during the ending. The options
menu and ending credits remain untranslated, as they rely on
a graphics format that has not yet been determined.

ROM INFORMATION
There are various floppy and hard disk images of Steam
Heart's, but this patch is ONLY guaranteed to work with the
following hard disk image. There will be problems with other
images, so it is recommended to use the one shown here.

FINAL THOUGHTS
My first PC-98 translation! It's so much easier because it
uses Shift-JIS, compared to 8- and 16-bit consoles that use
their own methods of storing Japanese text, often without
kanji. So translating this game was a lot easier as a
result.

It's a straightforward game, too: a vertical shooter with
only two types of main gun, and three types of sub-weapon
(the one that lets you be invincible for a short time is my
favourite). It's certainly not the hardest shooter I've ever
come across, but the main draw (I imagine) is the inter-
level cutscenes with the naked ladies and crazy plot. Well,
this IS the PC-98, after all...

I was introduced to the PC-98 Discord channel, and several
guys there helped me out at the beginning, which was great.
The main thing was getting to grips with x86 assembly, used
by the PC-98, and it turned out to be not so difficult. Soon
I was able to change the text routine to take ASCII text and
convert it to the thin alphabet that the PC-98 has in its
internal ROM, plus deal with all the little things that go
along with it.

It's a pity that the options and credits allude me for now,
but I've put the options here, and I doubt many of you are
REALLY keen to know who was behind this game. Obviously I'd
love to make a complete translation one day, but someone
will have to get in touch with help on the graphics format,
because I've got plenty of other games to hack! See you!

Tools I used for this translation:
NP21trace (best debug PC-98 emu I've seen)
HxD (general hex editing)
WindHex32 EX (checking/touching up text)

Special thanks go to Celcion on the PC-9800 Series Central
channel on Discord, who gave me a routine to convert ASCII
to Shift JIS, making this translation possible.
