SNES9X is by far the most +complete and accurate Super Nintendo Entertainment System emulator to date. +Taking full power of the ATi-GX chipset and packed full of features that are +to die for after playing your games you'll never want to come back to +reality. + +SNES9X is a very popular open source emulator mainly for the PC platform, but +has seen many ports to other consoles such as the Nintendo DS, Microsoft XBOX +and now thanks to SoftDev the Nintendo GameCube! This is a straight port and +is not based on any previous SNES emulators that have existed for the +GameCube. You can get more information on SNES9X here from the below URL. +http://snes9x.ipherswipsite.com/ + +[What's New 2.0.1b8] +* Added: SD slot B options for freezes, sram and loading of roms +* Changed: SMB options no longer displayed in menus when run on a Wii +* Changed: Game auto resumes running after resetting when choosing the "Reset + Game" menu option +* Fixed (maybe): Reading of DVDs past the 1.36 GB barrier (Wii only) please + test! - svpe + +[What Was New 2.0.1b7] +* Fixed: Zip compressed freezes to memory card could become corrupted as the + file size changed - fixed this by deleting the existing file before writing + a new one if the file size increased. If the file got smaller or stayed the + same the original file is updated, using less of the existing file if the + actual file size is smaller. A check is made before deleting the existing + freeze file to ensure that there is enough space available for the new + file. Note that additional space equivalent to the new file size must be + available. If not enough space is available the original freeze is retained + and the user is informed of the lack of space. +* Fixed: If option to auto-load freeze was selected, joypad config would not + be restored since that is stored in SRAM. Resolved this for now by first + loading SRAM if any and then loading the freeze. Obviously having to have + both SRAM and freeze is not ideal, but this gets the job done if you have + enough space on your memory card, SD card, etc. +* Added prompt when returning to the menu with autosave enabled allowing the + user choose whether or not to perform the save. Press A to save or B if you + don't wish to save. +* Added optional verification of Gamecube memory card saves. After writing + the file it reads it back in and verifies that the written file matches + what was to be saved. If it doesn't or if there was a problem opening the + file it reports the problem to the user. Set this option in the preferences + if desired. +* Added Reset Gamecube/Wii menu item +* Experimental DVD support for reading beyond 1.36 GB barrier on Wii. I have + no way to test this, so please report on whether or not it works! Based on + svpe's code. + +NOTE: due to changes in the settings, this version will reset your emulator +options settings, so if you had saved preferences you will need to make your +changes to the emulator settings again and save them. + +[What Was New 2.0.1b6a] +* Fixed: Going up a directory when selecting a rom on a DVD wasn't working + +[What's Was New 2.0.1b6] +* PAL Wii support - no separate version necessary! - eke-eke +* PAL roms now play at correct speed via internal timer, ntsc roms still use + more accurate VSYNC timing - eke-eke +* Zipped freezes to memory card - take 9-12 blocks or so - based on denman's + code +* Added option for auto save and load of freezes.

If you wish to use an SD card +or SMB share, you must create an SNESROMS and an SNESSAVE folder at the top +level (root) of the card or share. Put your roms in the SNESROMS folder. On DVD +you can either place your roms at the top level, or optionally you may have an +SNESROMS folder at the top level of the DVD, in which case the game selector +will default to showing that folder when first entered.

To use this +feature simply save or load SRAM to/from SD card or an SMB share. + +The only thing to be aware of is that Snes9xGx requires that the SRM file have a +name that is the rom name (not necessarily the same as the file name!) with .SRM +at the end. For example, the game "Super Mario All-Stars + World" has a rom name +of "ALL_STARS + WORLD", so the SRAM file should have the name "ALL_STARS + +WORLD.srm". You can see the rom name for a game by loading the game - the rom +name is shown in the information that is briefly shown at the bottom of the +screen. A perhaps easier way to find the correct name is simply to load the game +and then save SRAM to SD or SMB and look at the filename that Snes9xGx uses. +That's the name you should use when importing an SRAM from another platform. + +To use an Snes9xGx SRAM on another platform just do the opposite: save SRAM to +SD or SMB, and then copy that saved SRAM file to the other platform.

This means that it will allow the +GameCube to connect to a shared folder on a Windows XP or linux samba box, and perform +basic file functions. + +Known Restrictions + +TinySMB-GC only supports the LM1.2X002 protocol. THIS IS NOT THE MOST SECURE! +However, it does NOT transmit your password over the wire, so it's reasonably safe. + +How do I use it? + +TinySMB-GC is developed with devkitPPC and libOGC, therefore you should be using this +development environment. Put simply, it won't work with anything else! + +TinySMB-GC uses the TCP-raw form of SMB on port 445. + +The Functions. + +int SMB_Init (char *user, /*** The logon user - MUST have share access rights ***/ + char *password, /*** PLEASE USE PASSWORD SECURITY! ***/ + char *client, /*** Machine ID, whatever you want to call the GC ***/ + char *server, /*** Machine ID of share server ***/ + char *share, /*** Share ID ***/ + char *IP); /*** IP of share server ***/ + +SMB_Init is used to establish the connection, authenticate and attach to the share. +Obviously, this must be called successfully before any other function. + +void SMB_Destroy (); + +SMB_Destroy takes care of releasing the internal socket of TinySMB-GC and should be +called when the SMB functions are no longer required. + +int SMB_FindFirst (char *filename, /*** The file mask to search for ***/ + unsigned short flags, /*** Search criteria flags ***/ + SMBDIRENTRY * sdir); /*** An SMBDIRENTRY to hold directory information ***/ + +Similar to MS-Windows, to search for a file or directory, use this function to determine if the +file already exists. The SMBDIRENTRY simply holds basic information on each entry retrieved. + +int SMB_FindNext (SMBDIRENTRY * sdir); + +Called to continue a search started with SMB_FindFirst. + +int SMB_FindClose (); + +When all searches have completed, call SMB_FindClose to dispense with the search handle. + +SMBFILE SMB_Open (char *filename, /*** The filename to open ***/ + unsigned short access, /*** Access method ***/ + unsigned short creation); /*** Creation flags ***/ + +This call will open a file on the share.

However, the onus +is on the developer to maintain the offset value when reading / writing +sequentially. + +You should also be aware that these functions should only be used to read/write +blocks up to 62Kbytes.
