SNES Myth menu releases

[mic_]

Hint: left and right skips one page up/down in the list   The menu uses a blocking key-reading function (a remain from the old neoflash code). But I suppose it could be changed.

Detecting the SRAM size is trivial since that info is stored in the ROM, so that's already done. The tricky part is to determine the SRAM mode, i.e. how and where SRAM should be mapped into the SNES's memory space for a given game.

Yes, I know, but left/right somehow ALWAYS manages to leave me the maximum number of up/down press away from the file I want.

Then maybe make THAT a variable you can change.

The thing is, there are 8 different configurations to choose from, and it's not like it's obvious which one you should use (if it was I'd already have written the code for selecting it automatically). And who wants to try out a bunch of different settings to see which one works?
The solution is probably to take a look at the source of some decent SNES emulator and see how they do their SRAM detection, then implement something similar.

You can use the code of SNES Plugin...It virtually supports every possible combination

@mic

after weeks i test your menu  (0.55) have time now for retro  and i must say it is fantastic realy fast loading times per sd.

but 2 i have two points:

everytime i reset to the menu (set it in X menu = to menu) i must set it again everytime 
and can you change the background  or can you do some alternatives... *g sorry i don't like it. haha

but man thanks for the menu it is awesome

[mic_]

everytime i reset to the menu (set it in X menu = to menu) i must set it again everytime 

* Support for changing some of the default menu values through a SETTINGS.TXT file in the /MENU/SNES directory on the SD card.
   Currently recognized settings are:
   START_DIR=/SOME/DIRECTORY      start in this directory instead of /SNES/ROMS
   RESET_MODE=0-2         0=to game, 1=to menu after 3 s, 2=to menu
   REGION_FIX=0-2         0=off, 1=quick, 2=complete

[ronaldo_76]

omg shame on me...

where must i put the settings.txt ? i have non on the sd card. evertime i switch to sd mode it is a error message second time it works. non settings.txt was created!

where to put it?

/SNES/ROMS/
/MENU/SNES/
/SNES/MENU/SNES

??

sorry and thanks

[mic_]

It should go in /MENU/SNES if you use v0.55.

[ronaldo_76]

it works great mic! 

thanks for the hard work you invite in this project...

keep up the good work!!!

v0.56 of the SNES menu has been released: http://code.google.com/p/neo-myth-menu/downloads/list

A youtube video showing some of the improvements: http://www.youtube.com/watch?v=XTyMfxzZBn4

New in this version:

* Faster SD loading (at least if your core FW is 2.4 or later). The transfer speed has been increased about 15-20% (I get around 160-170 kB/s with my SanDisk cards).

* Added support for 48 Mbit ExHiROM games when loading from SD.

* Added some SRAM type detection for HiROM games when loading from SD.

* Fixed some bugs in the region fixing code.

Some games that now can be properly loaded that weren't working before:

Donkey Kong Country 2
Donkey Kong Country 3
Mario no Super Picross
Romancing Saga 2
Romancing Saga 3
Seiken Densetsu 3  (requires "Autofix region" to be set to "Complete" on PAL consoles)
Tales of Phantasia

It´s good to see that your Myth Menu is still improving! 
Maybe at christmas I will have time to add some Action Replay and Game Genie Codes to your library. 
Can you please post a short faq, how the code has to look like?

Thanks in advane!

The cheat database code (http://code.google.com/p/neo-myth-menu/source/browse/trunk/SNES/NeoMythMenu/cheats/cheat_database.c) contains tables for each game:

Code: [Select]

const cheat_t megaman_x_u_cheats[] =
{
        {"C2B91497", "Infinite Energy", CODE_TYPE_GG},
        {"7E0E8F01", "1 Shot Kills Everything", CODE_TYPE_AR}

First column is the code, second column is a description, third column is whether the code is a Game Genie or Action Replay code.

And at the end of the file is a table that maps the code tables to a certain game:

Code: [Select]

const cheatDbEntry_t cheatDatabase[] =
{
        // Megaman X (U)
        {0x4CC2, 0xB33D, megaman_x_u_cheats, NCHEATS(megaman_x_u_cheats)},

First two columns are the checksum and checksum complement from the ROM (can be read from the SNES header in the ROM). Third column is the code table for that game (as described above), and the last column is the number of cheats for that game.

Thanks. How can I mount the SD card on boot? I don't want to push R

Continous scroll if holding a dpad direction would also be nice.

OK. That´s easy!

You can be sure, I will send a *.TXT file with added cheat database...

Currently you can't. I might look into that later.

Should be easy enough to add.

What I'm currently working on is SD writing support. Not mainly for automatic SRAM saving-and-restoring, but to use the SNES Myth as a cart dumper. I.e. dumping the contents of the boot cartridge that you attach at the back of the Myth to a file on the SD card. I've already successfully dumped a ROM (though it's really slow right now - took about 3.5 minutes for a 4Mbit cart). It might be possible to dump the SRAM from original cartridges as well.
