Ok so I tried messing w/this eagle program a bit and I honestly don't have the time to invest in learning this program right now. How much would you charge to do it for me and send me the files needed to order these boards. Wanted adapter board for snes to m27c160 eprom. I can provide desired board ...

Just wondering if someone might be willing to do this for me? When the game loads I want it to have a separate splash screen with a message.

Basically I want a repro to state it's a repro on the screen and such.

Compares all the cheaper sites.

Wow that is pretty cool, it has two china sites listed under $200 for 300 boards.

pcbway $194 shipped 11 days
itead studio $197 shipped 19 days

Wonder how quality is.

.6 not .06 lol that's the confusion. edit: I just realized Most snes boards dont fill the entire case up like a troy aikmen 2 mask rom board. I would not need those carts anymore. As long as I offset the chips to go outside the board area, space will not be an issue as I thought. Amazing what comes ...

I'm just seeing the options it was showing me.

.06mm for the thickness for the adapter board. When I say 1mm extra space, I mean currently if you have a snes board in case there is about 1 mm extra between the rom and the case as snes board lays. If I were to put an adapter board in between them, there is not a whole lot of room to add pins as w...

Ok looking into this some more. Seed appears to be the best option. The snes case does not have much room. It appears the eprom pins would have to be trimmed at the very least. Do you see any problems going with a pcb size of .06mm. It looks like the snes pcb is about 1.5 mm thick. I think I have ab...

Like I said before, the A lines are simply a binary representation of the physical memory address the CPU is attempting access to. You trying to understand what is going on with that mindset (facing how the cartridge works as math equations) will have a big effect on how you see this "repro ma...

Awesome, thanks for that. Wow I just got this I think. Due to you writing "Snes A21". The snes system board is pulling information to A21 on the system board. That A21 was confusing the hell out of me, it never clicked to me to think outside of the game board/eproms. So if I am reading thi...

I'm trying to learn all this stuff but I swear this is like learning a foreign language when you come into it w/a complete lack of any of it and I mean zero with a capital z. I have had many times now where I just had to walk away and come back days later. My main thing right now is comprehending th...

Ha! Yeah the jag was not as good as it should have been, but it is a badass looking system and some games were pretty cool.

According to this: you need a 74hct139

edit: well that is for eprom, just noticed you are doing eeprom not sure if it is the same.

Thank you. It works now. I had the ground to OE and OE on board to nothing.

So basically the whole chips still needs to be rewired anyhow. After moving the pins like you said you are left with this.
