I've been developing firmware updates for the Retrode.

The latest candidate is a firmware with improved SMS/GG support.

The BETA firmware adds SRAM save support, Codemasters support, and a bunch of fixes for cart identification.

I also made a working Mark III Plug-in that allows support for Japanese carts and Sega Card/My Card using a Card Catcher.

If anyone is interested in BETA testing, then PM me on the Retrode forum.

Happy Holidays!

If you need help with any unusual cartridges I could help.
In particular I presume that few Korean games will work out of the box. You can refer to meka.nam for checksums and Meka mappers.cpp for some references there.

Yes, no Korean mapper support, yet.

The mapper seems simple enough.

I'd probably want to get my hands on a Korean mapper cart to test the coding.

I'll try to look around for a test cart.

And I thought I was done with mappers after I got the SMS and GG Codemasters carts working...

:)

There are dozens of different Korean mappers..

Sounds like the NES mapper situation.

A bit too obscure for me to attempt to implement comprehensive support. It'll take someone with extensive interest in Korean carts to get done.

I'll limit my effort to adding the Korean mapper listed on the Mapper page that maps Slot 2 using $A000.

Much less extreme :)

I own many of those carts, I dumped them and implemented the mappers in MEKA. So I can answer some questions or test them if needed.

The dumps database that refers to mapper is:
https://github.com/ocornut/meka/blob/master/meka/meka.nam

MEKA is old crappy code but you can easily infer things out of the code:
https://github.com/ocornut/meka/blob/master/meka/srcs/mappers.h
https://github.com/ocornut/meka/blob/master/meka/srcs/mappers.c

Something I've learned over the years:
Just because [your] thoughts of how code should be have evolved is no reason to insult your great projects of the past.

I'm about done with the SMS/GG firmware update for the Retrode.

I implemented GG EEPROM save support. There are only five GG EEPROM carts but I wanted to add full EEPROM read/write support for completeness.

I'll be publicly releasing the firmware on the Retrode forum soon.
