Re: SRAM decoder 74LS139 for 27C160/27C322 LoRom/HiRom
27C322 maskrom "mask" ROM means something. A 27C322 is not a "mask" ROM. Instead, it is an UltraViolet-Erasable Programmable ROM. Different ICs put different functions on different pins. Compare, for example, the pinout of the SST39SF040 (A18 on pin 1, /WR on pin 31) to that of ...

Re: SNES game PCB cartridge with chip vs battery to save
two possibilities I can think of: 1 - could use FRAM or similar non-volatile chip. not available much as a 5V part, and Sonic 3 for MD/Genesis was the only cart that I know that used FRAM. 2 - a game could save to the same flash memory that's holding the game. this requires (potentially) extensive ...

SNES game PCB cartridge with chip vs battery to save
Hi for all, Can you explain me please, why there is no possibility to make PCB for SNES games with chip to save the game vs battery? I can see here for example, that on ALiexpress, Chinese propose game version with battery and without: https://i3.imageban.ru/out/2020/06/15/b63cc0c5925c0e20cea745241e...

Hahaha you should talk with some of the other people here, they are my Senseis! Maybe, but I dont think that they made something like you, your website. You shared your knowledges with others. I wish that God of Nintendo will protect you forever from all kind of virus, like Corona and other shit......

Re: how to use Use 27C040 in PCB for M27C801
I've heard of EasyEDA a lot but that board rendering is really nice. I need to check it out myself. I've been using the same version of Eagle for so long, over 6 or 7 years now, I should probably try something different! Glad my site helped you out. Always nice to hear :) :wink: You welcome. Glad t...

I use EasyEDA. https://easyeda.com/ PS: I know you web site. I lear many things from your site. You make me wanted to do i...
