Hello Dhampird,

If you want to compare, here my complete schematic to multirom 2 (the pins indicated is to SDMMC 2.2+ brazilian version, but is based in original version on Sharksym homepage).

Hello, thanks for that diagrams Taylor, very professional diagrams.

Capitan_Goto, my diagrams are based on Sharksym original diagrams, i mean that those diagrams are not my original design, only i just followed some korean info webs to put here a MultiromII diagram to understand the install more easier, only that. I´m not planning build or produce that MultiromII device, because original design is not my property, original property is Sharksym, if i´m right.

Those diagrams i uploaded are only a way to better understand the original diagram. Anyways, I have to tell that some files will be needed to allow test/work this MultiromII mod, those files are Bios 4.10 and Mfash.com made by Sharksym, without that files nobody can operate the MultiromII expansion for now, until Sharksym release to the public that files someday. Idont know if that files will be released some day or always will be private. I dont know if the MultiromII is available for purchase in any Korean site.

Ola Capitan Goto.
Em portugues: Nao penso em produzir, ja entrei em contato com o Yeongman Seo (sharksym) para
enviar os arquivos de producao para ele, mas nao obtive resposta ainda. Acho que ele nao quer produzir
e provavelmente nao ira disponibilizar os arquivos bios 4.10 e novo mflah.com
Mesmo assim, mantenho certa esperanca.
