Can you help getting more info about those carts?
Cart name
Notes for chip search:
  • Use "+" as delimeter for all fields (except "cart name", where space is used); if many values are entered, all of them must appear in the cartridge then; case is not sensitive
  • "Mapper" is the actual mapper used by this cartridge hardware (might not match the one at wiki.nesdev.com, as at the moment I was analyzing this cartridge, there was no mapper assigned to it, so I had to assign my own number for testing)
  • "Original mapper" is the mapper used by licensed version of this game (for multicarts, it refers to mapper of the inside games, so 0+2 means this cartridge can run NROM+UNROM games)
  • Order in which you put values doesn't matter (you can write 7400+74138+7400 or 7400+7400+74138 to search for a cartridge that contains at least two 7400 chips and one 74138
  • Some chips (like PAL16*8) appear in cartridges as 16V8 or 16L8, so be sure to check both posibilities
  • Same goes for memories - type 27F080 to search for 32 pin memories, 27512 for 28 pin with two chip enables or MASKROM_1M_DIP28 for 28 pin with one chip enable
  • Same goes for mappers - some examples: AX5904(MMC1), AX5202P(MMC3), PT8154BM (9112MMC3), AX5208C(VRC4), 23C3662(VRC2)
  • Good news is that you can use wildcards, so 74139+*MMC3* will search for any cartrige that has at least one 74139 and MMC3 chip in any version

Codemaster' CME-01 and Cosmic Spacehead rev-eng

I've got [url=http://bootgod.dyndns.org:7777/profile.php?id=4588]Cosmic Spacehead[/url] for testing. This is the only known game that contains Codemasters' CME-01 DIP28 chip. This is remastered Aladdin version of `Linus Spacehead Cosmic Crusade`, with the following differences (maybe there more):
* Cosmic Spacehead is dated 1993, while LSCC is 1992 (this is in fact the only NES Codemasters game dated 1993, others are 1992 or 1991)
* Cosmic Spacehead uses new Codemasters logo 
* The splash screen is different
* There is something called "2 player pie slap" in Cosmic Spacehead
* Plus the shell shape looks very different from standard NES shells.

                   '---------'
* Mapper is clocked with external 10MHz ceramic resonator (blue thing)
* There is 4 bit inner PRG bank, like in mapper 71:  [....pppp] at $c000-$ffff 
* There is 3 bit outer PRG bank, like in mapper 232: [...PPP..] at $8000-$bfff
  (with one additional bit)                              ||+---- pin 9
                                                         |+----- pin 10
                                                         +------ pin 8
* Pin 23 = PRG /OE <= /ROMSEL or not CPU-R/W
* Pin 24 = PRG /CE <= '1' when copy_protection_enabled else '0'
  Reading $0000-$ffff while copy protection is enabled returns $EA)
* After power up, copy protection is enabled. To disable it, CIC+RST must become low,
  and then - CPU read from $f000-$ffff must happen. If CIC+RST is floating, game won't work.
* For current state of knowledge, CPU D7/D6/D5 do not seem to affect anything
* Above chip and PRG-ROM are powered from +4.3V (1n4004 diode in series with +5V)
* Pin 11 controls N-mosfet. If it goes high, it can cause very high current to flow from VCC to GND.
  However, I wasn't able to toggle this pin high.
