For SMS games this thing used discrete mapper located on separate board. Kind of tower of power (:

@krikzz it looks very soviet

@EstebanVLobos Not enough dip components for complete soviet style (:

@krikzz Amazing! Does it still work? :D

@pitto No. Unfortunately i took some components when they been need for another device. But i think it can be repaired.

@krikzz Love stuff like this. Any other prototypes still around?

@TonicoX86 yes, i still have some early hand made boards. Some even older than this one. Very first prototypes was one-game carts programmed via usb.

@krikzz Missing some fast 8-bit AVR in upper center? With MMC+FatFs code by ChaN ( @Philips_NE555 )?

@x4a5448 @Philips_NE555 Atmega16 with my own damn buggy fat core.

@krikzz Krikzz If you don’t plan to release a Master System USB flashcart anymore, could you please consider turn the pcb project open source?

@_fabdigital_ You mean first generation of Master everdrive ?

@krikzz Эхх, вот бы у меня ЛУТ так же хорошо получался )) Половину дорожек приходится маркером дорисовывать ))

@iorange_man бумага на которой печатается плата и качество полировки платы наверно смое главное в этом деле. Хотя процесс проутюживания и травления тоже влияют на качество результата

@krikzz Congrats :)

@krikzz Nice!

@krikzz Where it all began Or "how it started" but not "how it's goin"

@krikzz WoW!

@krikzz When you said 2009 I didnt think much of it, until I realised 2009 was 11 years ago 😳

@krikzz Reminds me of an Intellivision board. Very cool

@krikzz 2009 was it only 11 years ago? I thought your stuff had been around a lot longer.
