Graphics pack Installation:

I have uploaded the graphics packs here:

http://www.rogepost.com/dn/z8j6/graphics.7z

However, they are available other places as well.

Copy the contents of the graphics packs for the following games into these folders.

Game Name: Far East of Eden Zero (J)
Graphics go in folder: D:\graphics\Far East of Eden Zero

Game Name: Far East of Eden Zero - Shounen Jump no Shou (J) [!]
Graphics go in folder: D:\graphics\Far East of Eden Zero - Shounen

Game Name: Momotarou Dentetsu Happy (J) [!]
Graphics go in folder: D:\graphics\Momotarou Dentetsu Happy

Game Name: Super Power League 4 (J) [!]
Graphics go in folder: D:\graphics\Super Power League 4

You can also rename to match your rom names/copy the included sram files into the ZsnexBox\sram directory so you don't have to setup each game. If you copy these over, the games should start without any configuration. 

There are issues with Momotarou Dentetsu Happy (J) [!] (hangs at the Hudson logo) and Super Power League 4 (J) [!] (graphics corruption) that have to do with the emulation of ZSNES, and they have nothing to do with the graphics packs themselves.

Star Ocean and Street Fighter Alpha 2 do not use graphics packs any longer nor will ZSNES load them if they are present.
