carlossless / gbfc Goto Github PK

For version two of the gbfc I would like to have:

• MBC5 compatible mapper. Probably based on a CPLD.
• 1Mbit FRAM
• 8Mbit Flash

JTAG pins are placed in the wrong order. They should have placement like this:

There needs to be a trigger in place to put the gbfc in to bootloader mode. This trigger could possibly be a push button and need to be held down the applying power to the chip.

Current design lacks a diagnostic led. It would be pretty beneficial to have one or two to easily display hardware failures or just general diagnostic.
