Re: SEGA GameGear Flash Cart - Custom Electronics

Hi Kiruha2012, Actually they already made an SD based GG Flash cart. My project is just for fun, to build something for electronics Hobbyists. :) If you like to fiddle with electronics then my Projects are perfect, but you can always just go and buy one for around $75 - $120 Dollars. So in short: Go...

Re: SEGA GameGear Flash Cart - Custom Electronics

Snow_Cat! THAT IS AMAZING WORK!! This is a lot of work you've done here. Very awesome. Do you think you'll be able to actually figure out the traces for the uncovered sections of the PCB? That would be awesome. I guess the use of the Discrete IC on this RETAIL Eprom cart, is being used for chip sele...

Re: SEGA GameGear Flash Cart - Custom Electronics

Ok Sounds good. I'll be looking into this later this month once I get my hands around this Altera VHDL language. I might have a better idea at that point on how to attack implementing a custom Mapper. That's really bizarre regarding SMSpower? I'll send MAXIM the site admin a MSG regarding that. Weir...

Re: SEGA GameGear Flash Cart - Custom Electronics

Hi Snow_Cat, You should Register and jump in on the Topic I have opened on SMSPower for this 512Kb design. Charles MacDonald was interested in the Specs for the Mapper chip layout you put together for the Eagle Library. Anyhow, here is the link to the thread. http://www.smspower.org/forums/viewtopic...

Re: SEGA GameGear Flash Cart - Custom Electronics

Yeah true..... it makes sense. Have you ever checked out Tototek's carts? it looks like he does allot of his Memory mapping/paging with CPLD's & FPGA's or other Microcontroller's. There was one version of a Gameboy Flash cart I found off Reiner Ziegler's site, that used a CPLD to emulate the Memory ...

Re: SEGA GameGear Flash Cart - Custom Electronics

Hey Snow_Cat, Can you Rig up a generic TQFP 44 Pin LBR file for me? You seem to have quite the Nack using Eagle. More so than I do. No designations needed for the pins at this point. I wasn't able to find one on the Eagle website. If possible have the first Bottom pin on the left designated as Pin 1...

Re: SEGA GameGear Flash Cart - Custom Electronics

Yeah I did actually try that already and didn't have any luck.

I'm hooking up the Original ROM to my Logic Analyzer hopefully sometime tomorrow.
I might be able to find something from the readings I collect......well hopefully.

I'll see how it goes. :)
