I forgot the CS line is used to synchronize packets/byte between master and slave.
A direct implementation is impossible as there are only 2 output PINs on the joyport.

Crap...

I'm putting this here as I don't if I'll ever find time to implement it. SPI is a rather simple bus. It only uses 4 pins, SCK, MISO, MOSI, CS. Long story short, joyport SEL and CLR can be used for SCK and MISO, any of the D0-D3 lines can be used for MOSI, and CS can be directly wired to GND. The cod...

Update done!

Here are some images of the pachinko controller guts. Although it was sold by Coconuts Japan, the PCB seems to have been designed by Hori. http://blockos.org/releases/pcengine/hardware/Pachinko/thumb/pachinko_back_00.jpg http://blockos.org/releases/pcengine/hardware/Pachinko/thumb/pachinko_back_01.j...

phpBB 3.1.9 is out... Expect an update this week (whoever might be reading this... I'm talking to you Google bot!)

Here are the scans of the manual:

• Cyber Stick
• Micomsoft XE-1 AP
  • page 1-2
  • page 3-4

It seems that the code after l_f6cd is about moving hgfedcba into 0000bagh . Bits a and b being Select and Start. Anyway the 19 lines of codes that computes this can be reduced to : lda $2a30 asl A ; A=gfedcba0 carry=h rol A ; A=fedcba0h carry=g bcc l0 ; if(carry != 0) A |= 0x$02 ora #$02 l0: ; A=fe...

I think I found the routines that detects and read an analog joypad. According to Gamesx wiki , only 4 games (all by NEC Avenue) are supporting analogue controllers: Afterburner II Forgotten Worlds Operation Wolf Outrun This is what you'll see with Operation Wolf: http://pcedev.blockos.org/download/...

This may be an old news but the official NEC PC-FX SDK is available for download (here).

You can also find SDK for a bunch of other platforms here : http://www.emuparadise.me/sdk
Grab them while you can because I don't think this page will last long
