Title: Fire 'n Ice, with sram saving
Post by: Drakon on February 22, 2014, 08:05:08 pm
I decided to test my new found nes asm skills that I gained from working on other projects.  I worked last night and this morning and hacked in fully functional sram saving to the fire 'n ice rom:

For something done in a night and a bit of a morning I'm pretty proud.

You know the Japanese version had saving originally?

Really?  I had no idea.  Why would they remove the saving feature in the american release?

Probably to cut costs, a la Metroid. Although Metroid had a SNROM chip, it just didn't have the save battery.

Did metroid come with a ram chip and was just lacking the battery / diode circuit?

*looks at the pcb pic on nescartdb*

Yup.
