/*-------------------------------------------------------------------*/
/* What is pNesX? */
/*-------------------------------------------------------------------*/

It is a NES Emulator to play on PSX.
It can be played only with PSX which can read CD-R.
It is a speed like 1/10 of the actual time.

/*-------------------------------------------------------------------*/
/* for Developers */
/*-------------------------------------------------------------------*/

It won't be developed any further with being disappointed.
Continue the development by all means because source file is introduced
to the public.

/*-------------------------------------------------------------------*/
/* About the source file */
/*-------------------------------------------------------------------*/

There is no limitation in the modification, the distribution, and so on.
Hope that it can have a modified source file introduced to the public.

It can be played only with PSX which can read CD-R.

/*-------------------------------------------------------------------*/
/* What it does */
/*-------------------------------------------------------------------*/

Basic NES hardware.
Sound isn't mounted at all.
The ROM file which supports with it is the file of the iNES format. (.NES)
It will supports with a mapper #0,1,2,3,4.
It doesn't supports with the ROM of 1MB.
Keep the contents of the backup RAM in the memory card. (Only a Slot1)

/*-------------------------------------------------------------------*/
/* How to work it */
/*-------------------------------------------------------------------*/

Write all the necessary files in CDR.
It isn't written here to be detailed.
It thinks that it can obtain various information on the Internet.

Reference link
PSX CD MAKING http://www.arrakis.es/~ccarloss/

Next make a ROM list file if you can make "PNESX.EXE" which is
an executive file to play on PSX.
Write title of the ROM and a place in this file.
Make it with suitable text editors.
A format is the following.

[title]
FileName=file name

[title]
FileName=file name

...
...
...

The repetition of this.
A title and file name is a maximum 40 characters.
Do referring to "ROMLIST.INI" of the sample.
The number of the maximums is 500 title.

Make a CD by the following directory composition if you can
make "PNESX.EXE" and "ROMLIST.INI".

[Root directory]
PNESX.EXE
SYSTEM.CNF
ROMLIST.INI

[sub directory]
romfile
romfile
romfile
...
...

[sub directory]
romfile
romfile
romfile
...
...

...
...
...

Put "PNESX.EXE", "ROMLIST.INI", "SYSTEM.CNF" on the route directory.
And put a ROM file as specifying it with ROMLIST.INI.
(NotejIt is said that only about 30 files can be put in 1 directory
in specification of PSX. It is said that about 30 directories
are a limits, too.

It doesn't play with PSX even if it has it with the CD just like this.
Write it after making an image file referring to PSX CD MAKING and so on.
In the case of me, A CCS file was made with a certain tool,
(A system area file isn't specified.), and an ISO image was made with
the next batch file.

ccs2iso.bat:
--------------------------------------------
echo off

if "%1" == "" goto usage

ccs2cti %1.ccs
buildcd -i%1.img %1.cti
stripiso 2336 %1.img %1.dat
copy /b 2336mx.iso+%1.dat %1.iso
echo Done!
goto end

:usage
echo Usage: CCS2ISO ccsfile
echo Ex.
echo Make test.iso from test.ccs
echo CCS2ISO test

:end
--------------------------------------------

2336mx.iso is the thing which read head 16 sectors of the suitable game
with CDRWIN.
Data type is Data - Mode2 mixed (2336)
I am sorry if it is wrong.

After that, Write ISO image with B's Recorder GOLD

/* About the program */
/*-------------------------------------------------------------------*/

A frame skip was taken because it was late (3 frames)
It can be changed by changing the value of FrameSkip being set with
pNesX_Reset().

It can't be compiled if comment out doesn't do delete() in the file.
A change may become necessary by the environment.

/* Thanks */
/*-------------------------------------------------------------------*/

Appreciate everyone who has the materials related to NES, PSX on
the Internet introduced to the public.
Especially, Mr. MaratFayzullin's and Mr. Y0SHi's document was very helpful.

/*-------------------------------------------------------------------*/
/* Postscript */
/*-------------------------------------------------------------------*/

It could be done somehow. However, it is late. What is it?
As for FCEMU, it is said that 60fps comes out. blue.

Before selling a certain famous RPG VII, it was good that
it could be released. I and II seem to play.

Well, good-bye. 2000/02/10 Racoon
