RELEASE: VBA LINK + E-READER

There is a VBA version with link cable emulation

There is a VBA version with e-reader emulation compatible with raw files

But there isn't a version with both emulations at the same time, that's why, using the source code of both versions, that's why I've done a merged version of both VBA in the same emulator. Here it is:

I'm not the author of the link emulation nor e-reader emulation, I only mixed both versions in one.

This is a merged of VBA-Link 1.73 (link since broken) created by denopqrihg and VBA-Reader
created by caitsith (http://www.caitsith2.com/), they are the real authors of these emulations

 

Source Code
All versions of VBA publish the source code and I will not be less
(source code has been added to the download page)
 

Huge Thanks
VBA-Team for creating the emulator
denopqrihg for the link emulation
caitsith for e-reader emulation
ad2099 to testing this emulator and the save for FireRed & LeafGreen
