[QUOTE="qlb1234, post: 7026522, member: 348903"] Sorry to bump an old thread. To anyone who's still wondering whether there's a solution, the short answer is "probably yes". TL;DR: You can probably replace the SRAM on a genuine Pokemon Gold cartridge with an [URL='http://www.cypress.com/file/136591/download']FM28V020[/URL]. The main reason, as stated by qwertymodo at #11, and by BennVenn [URL='https://www.reddit.com/r/Gameboy/comments/4rkoyz/bennvenns_gbgbc_high_quality_reproduction_pcb/d528jj8/']here[/URL], is that [URL='http://www.cypress.com/file/136521/download']FM1808[/URL] (or other variants) doesn't support continuous read. Section "Pin Definitions" on Page 3 states that, Loud and clear. This feature - multiple read operations in one cycle of /CE - is a feature of majority SRAM chips, e.g. [URL='http://www.kynix.com/uploadfiles/pdf8827/W24257S70L.pdf']W24257[/URL]. Rabby250 at #12 listed some Pokemon games which won't work with FM1808: [LIST] [*]Yellow in Japanese region [*]Red/Blue in US region [*]Gold/Silver in any region [*]Crystal in any region except Japanese [/LIST] They're all newer Pokemon games (except that OP tried it on European version of Yellow, which was released in 2000, still works), as opposed to Pokemon Red & Green. So the wild guess "they continuous read RAM" may very likely hold true. But I can't imagine how this flaw introduces graphic glitches. The new generation of Cypress FRAM, whose name starts with "FM2", is capable of doing this. In fact, they even support continuous write, which is amazing if you're making a homebrew flash cart. The reason I kept using the word "probably", is that I have yet to try an FM28V020 on a Pokemon Gold cart. I bought a used one for this yesterday but it's still on the way. I managed to replace the SRAM on my EMS 64M cart with a FM28V100 and I didn't get [URL='https://gbatemp.net/attachments/dsc01858-jpg.2463/']the glitch[/URL] OP has encountered. I will order some FM28V020 and update as soon as possible. And for people who can't wait, just go for it. Update: Don't do it. It doesn't work. I was experiencing graphic glitch after replacing the original RAM with FM28V020. After I saved the game, the save file doesn't persist through reboot. Maybe we should wait for yet another generation of FRAM chip, the one which will be truly functional identical to static RAM.

Just between me and you, I mostly believe they honestly do. Even though they are selling themselves out, they still get to brag and gain some clout.

Sweet Baby Rays is like baseline for a decent/good bbq sauce, but nothing outright incredible

Stubbs is a pretty damn good sauce that I think you'll find on most grocery shelves as I don't think it's regional

Best bbq sauce I've ever bought on a grocery store shelf

smokey flavor that reminds me of beef jerkey on top of a really rich kind of bbq sauce. Heat level that is a nice zing, not overwhelming, but it tingles all the way down your throat
