Possibly :)
This one from the Arcade Otaku wiki has exactly the same layout:
Only difference is that I don't have the "Neo-Geo" buttons installed. Just a black plug.
BTW, sorry for hijacking the tread with all of this Egret II talk :D
Ahh I see. It was like that when I got the cab. I'm not complaining. I actually prefer it that way.
It also has a 7th hole that is blanked, so you can set up for both jamma, neo geo and 6-button fighters. In many ways I'm a purist, but not when it comes to control panels :whistling:
EDIT: When...
Gunlock running on my Egret II with no color bleeding :D
Not my best soldering job ever. All of the components has a pesky connection to a ground plane, so don't do this unless you have a good soldering iron and/or the skills not to fuck it up;)
I bought five new 29F400s for this project. Think I'll try with one of the extra four first :)
Good idea! I'll give it a go. It would definitely save me some money :thumbup:
The solder pad for pin 47. The 8/16-bit select pin.
Somewhere, yes. I think. You want a dump?
Awesome! I'll try to get me some PSOP-chips at some point, and a converter for my programmer. Probably gonna end up being way more expensive than just buying a repro cartridge X/
The pins on the SH2 should be good. I haven't touched those.
But...
Now I removed the 29F400 again, and of course I managed to rip off one to the solder pads that has a trace that goes under the chip :cursing:
There's a unused spot called "U5 28F400" on the back side of the security card, am...
Are there any specific steps that needs to be taken, when doing this conversion? I haven't been able to finde any useful information about the procedure anywhere, so I'm just sort of winging it :whistling:
Anywho, here's some pics:
The connector should be fine. The donor game worked perfectly before I did the BIOS swap.
I've reflowed all pins on the BIOS several times... no dice.
It has most likely been fried by ESD while I was handeling it ||
Oh well, at least I'll get to dust off my SMD soldering skills a bit more.
Okay so,
I have managed to flash a 29F400 with the custom SuperBIOS and I have replaced the original chip with the new one.
Problem is that now I'm just getting suicide garbage on the screen ;(
I removed the battery after installing the new BIOS, but did doing things in that order actually...
