Neon 64 0.3b

[johnson]

Hi  everyone

this great hack of neon 64 made by Visor lets do savestates with Dezaemon 3D SRAM emulation and screenshots for 64drive also save game  (s-ram) Without using controller pak, and support mapper mmc4

download in:

however, in everdrive 64 it can not permanent savestates. My question is if someone can change the everdrive menu to start the emulator with Dezaemon 3D SRAM ? and upload the savestates

i have not understand what need to run it and what is that sram savestate. please explain

[johnson]

with the everdrive 64 can't does permanent savestates because the Dezaemon 3D SRAM never implemented in the OS , unlike  64drive  where marshallh quickly update his menu. I read that maybe works in saturnus alt64 menu  if someone change the OS https://assemblergames.com/threads/neon64-with-savestates.64696/ but  I don't know anything about programming.

With this hack  you can save games like zelda, kirby whithout Controller pak and do temporary savestate  while you do not change games when you play, only press L + R for see the options.

I don't now if krikzz wants to activates the Dezaemon 3D SRAM  in the oficial OS  , in fact i'm thinking of buying the 64drive.

it's implemented since OS version 2.10

You have to tell the Everdrive 64 to use the Dezaemon 3D SRAM emulation save type for the emulator.

To do this, open the file save_db.txt which is in your SD card's \ED64\ folder.


And add the following lines to the bottom of the 'save_db.txt' file:


0x8979169C=4   (neon64 NES emulator v3 - Press L and R for savestates)
0x1974961C=4   (neon64 NES emulator v3 - Press L and R for savestates)

and it will probably work. It tells the Everdrive 64 to use the Dezaemon 3D SRAM save game method for two different versions of the emulator.

I can't test this, as I don't have my N64 with me, so it might be wrong. If this works, then please post to say so, and if it is wrong, then follow the tutorial:

and please post here the right line to put into the save_db.txt file.

[saturnu]

this is not going to work.
files with an extension like .nes are set to sram32 instead of sram96 by the OS.
infact it's just 1 byte that needs to be changed.

it looks like there is a 64drive checks in the source of neon 0.3b. (64drive.inc)
but it's just disabling the screenshot usb feature.

[johnson]

strange  after all, the emulator has a kind of protecion ? or something like that

[saturnu]

it's not a protection, it's even open source. ^^
the usb-screenshot feature is disabled, 'cause it's 64drive specific - the way the usb communication is working.
the 64drive can dump memory cartspace offsets native while running, the ed64 would need fifo routines inside the neon64 program.

Trying my luck here as well, coming from http://krikzz.com/forum/index.php?topic=5489.msg73696#msg73696
Did the X7 get the latest emulator incorporated, or do we still need to manually 'install' Neon64 0.3b ?

Additionally, Kerr Avon, there are 2 lines here for Neon64, but there's only 1 in http://krikzz.com/forum/index.php?topic=6126

Can you elaborate?

[jonesalmighty]

Setting the save_db wont work for this. It will have to come in the form of a menu update from krikzz.  If you have an ed 2.0, 2.5 or 3.0, you can use my unofficial official menu as I have already added support...

[Shadow_Zero]

Where can I find this unofficial official menu? (I have the X7)

Well spotted! I've added the the other code to the "Here are the known fixes for games/hacks/etc to save and load correctly" thread, thanks.

Why won't it work from the save_db.txt file?

[jonesalmighty]

Because loading the emulator does not use save_db, at least in 2.12 as it is hard coded... you can try it for yourself to confirm. I have added the correct sram settings in my unofficial official os in the meantime (see the changelog).

Hey jonesalmighty, I'm new here and maybe you're a celebrity around here (or I missed some post), but what is your unofficial official os and where do we find it??
