Homebrew jEnesisDS for GBMacro users :)

[xonn]

I came from this thread: https://gbatemp.net/threads/injecting-asm-code-to-homebrew.573855/
After some days of work (and a bit of luck), I have "hacked" the jEnesisDS emulator and I have included a screen swap just after rom selection.
This is great news for GBMacro users, because it open the possibility to play with Genesis games, at a great FPS and with SOUND!
You can download the NDS file from here: https://github.com/xonn83/jEnesisDS_macro
Enjoy and post your feedback (I hope not to have broken anything else...).

Recently, I have discovered that in some flashcards, you only get a black screen when a rom is loaded.
If this is your case, just press SELECT button twice, and the game will start.
This problem may have been caused by the replacement of some lines of original code to introduce forced screen swapping.

Hello Xonn, nice job ! sorry for my english I was searching for this kind of program for my DS XL Macro, it was really helpful !
Is there anyway to save state ? since we don't have the bottom screen with the option.
Many thanks

Due to savestate buttons can be only used in touchscreen, unfortunately there's no way to save state with this version ;(

I saw when I hit select and upper button, that does reboot the game, so maybe we can program an imput sequence to save and load ? It's been a while since I didn't code

The problem is that there's no source code to work with. It's necessary to find inside the hex code the correct place to replace some old code with new one. That's a very difficult task, and I must admit that I had an incredible luck finding a place to put swap screens code without breaking anything important.
