Cart DB #245: Rockman 7 in 1(JY-208)

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

Broken: PRG-A13,PRG-A19 bootup: 80 <- a001 JY208 This PCB consists of 2MB PRG-ROM (epoxy blob), 512kB CHR-ROM (epoxy blob), 32kB CHR-RAM, 74153 switch and mapper chip (epoxy blob). Mapper is MMC3 which behaves exactly the same like regular one with additional signals: PRG-A19, PRG-A20, CHR-A18 and CHR_MODE0, CHR_MODE1. Changing state of those lines is done by writing four bytes at $6000 (WRAM should be enabled first, so write $80 at $a001 and later after selecting game, write $40 to $a001 to protect it from furthes changes) CHR_MODE0 and CHR_MODE1 are special lines, connected to 74153 which enables one of four CHR modes: CHR_MODE1 | CHR_MODE0 | $0000-$1fff | $2000-$3fff comment 0 0 RAM from cart RAM from console CHR-RAM games with H/V/0/1 mirroring 0 1 ROM from cart RAM from console CHR-ROM games with H/V/0/1 mirroring 1 x ROM from cart RAM from cart CHR-ROM games with 4 screen Unfortunatelly CIRAM /CE is connected permanently to PPU /A13, so chosing mode 10/11 will cause bus conflict at $2000-$3fff so to fix that, some connections should be changed in the hardware. --- Here is list what writes are done on powerup and after choosing every game: **1st*** **2nd*** **3rd*** **4th*** | PRG | PRG OFFSET | CHR | CHR OFFSET | powerup 6000 <= 80,30,1e,b0 10000000 00110000 00011110 10110000 | | | | | RockmanX 6000 <- 00,20,7f,e0 00000000 00100000 01111111 11100000 | 256k | 256k (16*16k) | 256k | 256 | Rockboard 6000 <- 00,00,00,e0 00000000 00000000 00000000 11100000 | 256k | 0k (00*16k) | 0k | | Rockman1 6000 <- 00,70,00,f0 00000000 01110000 00000000 11110000 | 128k | 896k (56*16k) | 0k | | Rockman3 6000 <- 80,40,2e,e0 10000000 01000000 00101110 11100000 | 256k | 512k (32*16k) | 128k | 128 | Rockman4 6000 <- 00,80,00,c0 00000000 10000000 00000000 11000000 | 512k |1024k (64*16k) | 0k | | Rockman5 6000 <- 00,60,2e,f0 00000000 01100000 00101110 11110000 | 128k | 768k (48*16k) | 128k | 0 | Rockman6 6000 <- 00,c0,00,c0 00000000 11000000 00000000 11000000 | 512k | 1536 (96*16k) | 0k | | C PPPPPPPP Cmc pppppppp | |||||||| ||| |||||||| | |||||||| ||| ++++++++- 0=PRG line controlled by MMC3 (inner bank), | |||||||| ||| 1=PRG line belong to outer bank | |||||||| ||| (A20 A19 A18 A17 A16 A15 A14 A13) | ||||||||| ||+------------- 1= CHR A17 line controlled by MMC3 | ++++++++--||--------------- outer PRG BANK (A20 ..
