Irem H3001 - pinout
Used in games:
* Spartan X 2,
* Daiku no Gen-san 2: Akage no Dan no Gyakushuu,
* Kaiketsu Yanchamaru 3: Taiketsu! Zouringen,
* Ai Sensei no Oshiete: Watashi no Hoshi
This time unfortunatelly only basing on the [url=http://bootgod.dyndns.org:7777/profile.php?id=3849]images of Spartan X2[/url]. For furter testing need to wait if one of the above games gets cheaper.
The only quirk is about the unknown ceramic capacitor 331. It seems to go between GND and pin 39, but nothing more is wired to pin 39

Got the Spartan X2 cart, here are my new findings about Irem IF-H3001:
* Register at $9000 has 1Sc mirror abilities::
[code]
$9001: [MM.. ....] Mirroring
||
++- 00=V, 01/11=Single Screen A (CIR-A10 = 0), 10 = H
[/code]
* Pin 1/2 - does not seem to have any internal connections
* Pin 4 = PRG-A17
* Pin 3 = PRG-A18
* Pin 47 = CHR-A17
* Pin 39 = GND
* C1 is put between /CPU-ROMSEL and GND, not to pin 39
* Pin 33 - this is a delayed copy of M2: rising edge delayed by 40ns, falling edge by 14 ns
* Pin 38 - goes low during read/write cycle at $6000-$7fff (falling edge appears 40ns after rising edge of M2)
* Pins 9, 24, 39 seems to be internally shorted inside CHIP (=GND)
$9000
