Thanks to everyone in this thread you've helped me immensely. I am in USA running the ED64Plus knockoff everdrive device with the N-P switch on the top, running on a NTSC JVC LCD Monitor via RCAs.
I've got all of my N64 roms working with the official ED64Plus software, Alt64, and Alta64 as well. I am making this post to help folks and TBH keep things straight in my head, I've been futzing with this for a 2 weeks straight.
Some stuff I've learned:
-Some non-OEM Memory Paks can be used fine within games however the old MEMPAKTOOL by saturnu sees them as Rumble packs so you can't back up these if you're using the stock ED64Plus OS. This is a problem for me because I am using the stock firmware for the WWF No-Mercy save reason at the end of this post. He did modify this tool to disable the Rumble-Pack check to help someone a long time ago, however the file is no longer at the linked location.
IF ANYONE HAS THIS PLEASE HOOK ME UP! <3

hm yes it's recognized as 0x80 -> rumble pak
alt64 os only checks for the pak typ on the "format function" and "content view function".
beside that dumping and restoring doen't check for the pak type at all. :>
here is a version with disabled rumble pak check:
rumble_check_disable.zip
---------------------------------------------
-I went through every single game (That came on the 16GB SD with the device) and used a spread sheet to address the ones that didn't work, I categorized games not loading as
#1) PAL (B/W flickering video)
#2) FILE OPEN ERROR or
#3) BLACK SCREEN
#1) Flickering B/W PAL Games were mostly duplicates or sequels of Racing games. For non-racing games, I downloaded the Japanese NTSC versions (If not available in US-NTSC) and I just deleted those I couldn't find (There were less than 8-or-so I couldn't find a NTSC replacement)
#2) Most games that give a FILE OPEN ERROR simply need their names shortened. IE:
The Aidyn Chronicles - The First Mage (U) [!].z64 was renamed to
The Aidyn Chronicles-TFM (U).z64
(Some games after being renamed still wont start and load with a black screen, see below)
#3) Black Screen- Some Games need to be patched to remove Anti Aliasing (AA) I found a Rom set on the official Krizz Forum named
GSC - N64 A64 - 161017.7z and I simply replaced the games that started with a black screen (These are the games I pulled from the GSC Romset, and maybe some of the PAL replacements from the internet, I can't remember)
Banjo-Tooie (USA).z64
Bomberman 64 - The Second Attack! (USA).z64
Dark Rift (USA).z64
Duck Dodgers Starring Daffy Duck (USA) (En,Fr,Es).n64
Earthworm Jim 3D (USA).z64
F1 Racing Championship (Brazil) (En,Fr).z64
G.A.S.P!! Fighters' NEXTream (Japan).n64
Hercules - The Legendary Journeys (USA).z64
International Superstar Soccer '98 (USA).z64
International Superstar Soccer 64 (USA).z64
International Track & Field 2000 (USA).z64
Mario Party 2 (USA).n64
Power Rangers - Lightspeed Rescue (USA).z64
Quake II (USA).z64
Tarzan (USA).z64
War Gods (USA).z64
AFTER ALL OF THAT EVERY GAME WORKED! * EXCEPT
WWF NO MERCY!
To get it to work
I did 2 things: I first replaced the included rom with
WWF No Mercy (USA) (Rev A).n64 (Find it using google) just because (I think) I read that this version is NTSC and doesn't have the dreaded save game bug. THEN depending on what firmware/OS I was using on the ED64Plus, I used one of two save files.
If using the stock OS/Firmware (This is what I am using ) I placed & renamed the save file from the krizz forum (I attached it here in a ZIP) on the SD card under
DRIVELETTER:\ED64P\SAVE\WWF No Mercy (USA) (Rev A).FLA
IF USING ALT64/ALTA64 I patched (Using Saturnu's ED64-Saveswap.exe tool that I attached, however you don't need to patch it because I included the FLA in the
WWF_No_Mercy_SaveFIX.zip) the save file to be compatible with these newer firmwares/OS's....the only issue is that I CAN NOT GET IT TO SAVE THE GAME DATA TO THE SD CARD USING THE RESET BUTTON. On GameBlaBla's github he says that some games just wont save to SD so I guess sadly this is one? IF ANYONE HAS ANY CLUE HOW TO MAKE IT SAVE PLEASE SHARE!) To get the game to boot I placed the patched FLA file on the SD card under
DRIVELETTER:\ED64P\SDSAVE\WWF No Mercy (USA) (Rev A).FLA
Hope this helps someone, I really appreciate everyone who's ever posted in this thread !
