Reliving youth

When I was young I used to play Super Mario Bros. on my NES. Recently, I downloaded the emulator "NESTOPIA" on my windows laptop (Ubuntu Linux laptop has zsnes) and started with the Super Mario Bros ROM file. I still own the old Super Mario Bros NES cartridge. It seems that there is a lot that can be squeezed in a 27C256! I had opened some of the game cartridges to find that all of them were custom masked ROMs. Most of them had UMC logo. The original NES was based on MosTek 6502 core produced by Ricoh for Nintendo.

After a long time, I was glad to see the favorite welcome screen showing "Super Mario Bros" :-)
