Also has been tested with a Benn Venn Joey Jr. Mbc3 Games pro#Adapters source files / gerber available on GitHub as well!Įach flash cartridge was fully tested using a GBxCart RW v1.4 Pro from InsideGadgets and a working GBC console.Additional wires to WE, A20 (for F016/F032) and A21 (for F032) will also need to be soldered.These adapter can be soldered onto compatible 32-pin footprints on compatible MBC1 / MBC2 / MBC3 cartridges. 3 TSOP-40/48 ENIG Flash Adapters with castellated holes that support AM29F080, AM29F016, and AM29F032 flash chip.All cartridges have been thoroughly cleaned using 99% Isopropyl Alcohol and DeoxIT Gold contact cleaner to ensure maximum compatibility. Since all cartridges are pulled from original PCBs, there may be some wear on the cartridge connector itself. High Quality Shell (from Cloud Game Store) in one of 3 colors: Crystal, Clear Blue, and Clear Black.Brand new CR2032 Battery soldered onto the PCB.Preinstalled 2MB AM29F016 flash memory: each flash chip has been fully written and verified data to ensure proper operation.MBC3 and RTC Crystal has been tested and verified using the MBC3 test suite.Original GB / GBC MBC3 PCB with 256kb (32KB) Battery Backed SRAM.This cartridge was created by swapping out the Mask ROM included with the OEM PCB and replacing it with a flash adapter (also available for purchase) and AM29F016 flash memory chip. This cartridge includes an authentic OEM PCB with working Real Time Clock (RTC) functionality for use with compatible GB / GBC games. Other MBCs were for speciality uses only.This is a custom made, pre-built 2MB Flash / 32KB SRAM rewritable cartridge for Game Boy and Game Boy Color. The only Gameboy Color games that did not were the ones that used a RTC, which only MBC3 supported, or were unlicensed. MBC2 was an alternative option for those games needing just a small amount of battery-backed RAM on the cart.Īlmost everybody used an MBC5 for a Gameboy Color game, because that was the only MBC guaranteed to operate in the double-speed mode. MBC3 came later, and was only required if the game was too large for MBC1 or needed RTC functionality. Almost everybody used MBC1 for their Gameboy (DMG) games, unless they were unlicensed, were publishing a 32K game. Or did Nintendo just discontinue old MBCs in favor of new ones? MottZilla wrote:I think the point really was that MBC5 could do anything the previous MBCs could do and there was no point in using an older MBC.īut weren't higher numbered MBCs more expensive for the publisher? That was true on NES, where MMC1 was the cheapest and MMC5 the most expensive. So, if you had an MBC5 cart, you could play all games except those that use MBC3 + RTC, MMM01, TAMA5, HuC-1, HuC-3, MBC4, MBC6, MBC7, Camera, I used the following sites in figuring this out: ROM only games should also run just fine, as they have no reason to write anything to the bankswitch controller. Similarly, using a write value with 1s above the 2nd bit may select the wrong RAM bank.on an MBC5. Of course, if the old games do things like write in the 3000-4FFF area for ROM select on an MBC5 or use a write value with 1s above the 4th/5th bit, they may select the wrong ROM bank. Such writes would still be valid on MBC 1, 3 or 5. The only peculiarity is that MBC2 will only write to certain areas to switch ROM/RAM banks. The RAM Enable value (0A) should be the same as in MBC1, 3, 5. One would hope that since the RAM is supposed to be 4-bit, yet the bytes read in an MBC1, 3, 5 would be 8-bit, the game ignores the upper nybble. The 512bytes of RAM are in the same area as the 8+Kbytes of MBC1, 3, 5. MBC2 games are very similar ROM-select wise to MBC1 except that they use 4 bits in the same area as MBC1, 3, 5. All foreign television animated programs. Games with 512Kbyte ROM/32Kbyte RAM should also work, the write to MBC 3 is a free-to-air childrens channel launched on 8 December 2004, and appeals to children under the age of 15. Mortal Kombat 1 & 2 would not work in MBC3 or 5 because the manner in which it selects banks above 512Kbyte is not supported on those devices. MBC5 uses 9 bits to select a ROM page, but the lower bits are also in the same place. MBC5 supports 128Kbyte of RAM, but the selecting bits are in the same place. MCB1 uses five bits (512Kbyte or less) for selecting a ROM bank, MBC3 uses seven and they are in the same place. Both MCB 1 & 3 support banking for up to 32Kbyte of RAM in the same way as well as RAM enabling. MBC3 should be able to support any MCB1 game with a ROM size less than or equal to 512Kbyte. Actually, I would think that the majority of MBC1 (at least those released outside of Japan) and all MBC2 games would work fine with an MBC3 or MBC5.įirst, all the MCB1 games released outside of Japan contain no more than 512Kbyte ROM and 8Kbyte of RAM (with the exception of Mortal Kombat 1 & 2, which uses 1Mbyte of ROM and 0Kbyte of RAM).
