Thank you very much "piotr25691" and "BlueSupernova22".
To correct my previous posts this SSE4 build is 202209 version not 202208
I got managed to get DDRSN1J running (not in AVX2 😄) by replacing those dongle bin files.
After reading/studying/observing the entire thread and to summarize for preventing the issues of black screen, boot loops and/or closes after (take note of the ff.):
1. Use the correct version of PS2 bios (e.g. SCPH-50000_BIOS_Vx_JAP_170).
2. With Magicgate keys in bios folder (civ, cks, eks, kek)
3. With Python2.ini in "inis" folder with the correct path of HDDimage, Dongles & ID's.
4. Paths for those files use double slashes "\\"
5. Version patch of HDDimage, Dongles, HDDid, & iLink must all the same 'cos these are dependent to each other.
6. Make your PCSX2 not in "read-only" 'cos this won't also save your configurations in USB settings.
Regarding cheats (PNACH), it doesn't need to rename all your folders and roms to make it work including the PNACH file. It only needs the correct values in Python2.ini:
PatchFile= (use double slashes "\\" also)
PatchExtended=1
In PNACH file remove those double slashes "\\" in order to enable a cheat.
Enable also Game Cheat in your PCSX2 game settings.
"DDR SuperNOVA" (Japan version) requires Ethernet (not real Internet) enabled to pass Network Initializing:
Ethernet Device type = Sockets
Ethernet Device = Auto
Sadly, the PNACH for "DDR SuperNOVA2" (Japan version) is only works on 200707 but not in this 200710.
On the bright side, "DEAD END ("GROOVE RADAR" special)" is now present.
Looking forward for these games to be finally operational in MAME 'cos CHD's consumes less space compare to HDD *.Raw Files.
