You want a channel?
Here's a tip.......Search on the top right of forum it's called "Search" Press it, Type Custom Channels, you will find one on the 1st page......
Now go download autoinjectuwad off google, follow the README, inject the genplus boot.dol into the wad you have just downloaded, THERE YOU GO YOUR NEW UPDATED WAD, easy!!!

i did search but since that thread was back in may im guessing these NEW updates wont be listed there

Exactly, like I said YOU go and do some work yourself, inject the new .dol into the wad from there!
I'm glad of the power down update more apps/Emus are getting this feature now

 

[slaphappygamer]

awesome, im gonna inject this into a wad and then im gonna put all my roms on a usb device that i have vacant right now. i hope the lightgun works better in this version.

so i updated to this version from a version of Genesis Plus that i have had for a while. this version recognizes all of my roms which is great. however, when i try to perform load state it says the state loaded successfully but i get a black screen and i can't do anything.

anybody know how to fix this? i don't want to lose all of my save games.

You can use the Dol Forwarder for Genplus to load the emu without ever having to inject a new version

eke-eke has updated it with new save states, you NEED to REMOVE them and start over, that's why, guess you didn't read the update list!

so simply renaming the save states wouldn't work?

Am I totally missing a 16:9 correction video setting like FCE, VisualBoy and SNES has to shrink the screen down to a 4:3 aspect ratio? Standard is still pretty stretched on my end, just not as stretched as the "stretched" setting.

For now, I have it in stretched, and have the X axis set to a negative 30 or so, which kinda does the trick, but seems a little bit silly, especially if I'm just missing the actual setting to do it in-emu.
