While i am waiting for my parts to arrive from china for the MBC project, i am doing some research on some stuff on the SNES. So, I was doing research on whether i could just put a 29L3211 into a cart with the same pinout and if there is going to be any damage to either the cart or the flash chip th...

Any particular reason for this, other than the fact that you already have it? I mean, maybe it might be possible, but you're trying to shoehorn together a solution out of hardware that just isn't designed for the job. You might as well be trying to accomplish it on a Raspberry Pi, heck it'd be half...

I did not want to use either CPLD, FPGA or discrete logic, I wanted to use only an AVR for this job. I actually wanted to use an arduino Mega(Atmega 2560), because I happen to own one and it has enough IOs to do all the decoding on its own. Now, i did not know about these latencies, seems like these...

I have already got a solution in mind for getting either MBC1 or MBC5 emulated (because of their simplicity), when I have some freetime (unfortunately, I wont get any for some time :( ) I will try to get it done. If i have got something useful, I will for sure let you know ;) And MBC2 should be very...

Really, this is a job for a CPLD, not a microcontroller. However, assuming you currently have an Arduino, you could use it as a JTAG programmer for a CPLD such as the XC9500XL series, which would cut down on the entry cost of CPLD development. I sure know that a CPLD is capable of this job and it s...

I've given this some thought, an although an AVR is running at far greater clock speeds than the GB bus, (don't even consider Arduino) You will need logic doing your switching as the gameboy expects the data to be on the bus almost the same time as the /RD is asserted. If you were given 1 GB clock ...

The Arduino IDE is capable of doing something called PortManipulation, which is changing the state if the IO Pins in a really fast manner, but i am not sure if this is even fast enough. I found a blogpost in which someone was able to pass the data of the Nintendo Logo stored in the EEPROM of the Ard...

I recently coded a gameboy cartridge dumper for my arduino in order to get in touch with gameboy hardware, it works pretty well (after i lost my pokemon blau save in an attempt to dump the sram -_- but now i found the bug and it dumps everything properly). I have another project ongoing, but as long...

Your newest releases seem to have a startup bug, at least on my computer :( If I try to start Release 8 or 9 they won't even start, windows outputs an error after some time that there might be files useful to find out whats up: C:\Users\SNgamer\AppData\Local\Temp\WER6B21.tmp.WERInternalMetadata.xml ...

It is not that hard to break the SRAM based copy protections in the relatively few games that have them. Certainly easier than having to solder any jumpers. UCON64 usually does an ok job of cracking those protections. I tried ucon64 on some games, but it did only seem to get rid off the regionlock ...

Got it working now thanks to a tip from Danin. The problem was the size, the roms which did not work had to be padded to 8MB size (I use now LunarExpand for this), Super Metroid and also hacks do work flawlessly (if the sram is trimmed to 8KB by grounding A13 and A14 manually as i did in order to by...

so, it's me again. First off, the new host app is very well done (i know it does not belong in this thread, but i had to say this :D). Now i have tested my 12mb HiLoRom board with some other games, but i can't get some of them to work... I tested super metroid, which at first did not work and i foun...

I'd be happy to swap it out with the new revision for you. Please email me to handle that. thanks for your offer, but If there is no need for chainging the pcb's layout or any parts besides the JCIC, then there is for me no need to get the new version. if it is a common problem for the JCIC not to ...

Hi guys, I recently recieved my INL HiLoROM SNES 12MB Flash Cart and i am facing some problems: Firstly, I can not use the flash cart on my pal snes without disabling the CIC. I tried to get some information on how to use the TENNIS JCIC properly, but i could not find any (might just be, that i can ...
