+1. Keys:\r
+\r
+If it looks confusing to you, check this tutorial first:\r
+http://notaz.atspace.com/pico_tut/\r
+\r
+There are no default settings.\r
+When you start key configuration mode, black screen with dark-red squares will\r
+appear. Also there will be little 'control' on the top with the function\r
+name in it, and arrows on the corners of it. You can tap on these corners to\r
+select a function. You can also tap on these squares to bind that function to\r
+them. This way you can associate touchpad areas with game-controls or functions.\r
+I also made a small square in every corner of the screen to be used as a virtual\r
+button for some function, like save state. You can bind it as you like. To\r
+bind phone buttons, simply select the function you need, and press a button\r
+you want. To unbind any key or touchpad area, simply push or tap it again.\r
+\r
+When finished, select 'done' and press any key. You can also press 'Power'\r
+to exit.\r
+\r
+You need to bind 'pause emu' function to be able exit game when ROM is loaded.\r
+It is bound to 'back' button by default.\r
+\r
+2. Main Settings:\r
+\r
+Here you can set the orientation of screen and the drawing mode. The "fit"\r
+option will scale the image so it better fits in the screen, but some detail\r
+will be lost. "center" displays the game at the center of the screen, but\r
+non-fitting parts are not visible then. "fit2" is simmilar to "fit" but is\r
+a bit more stretched (fit modes are only meaningful in 0 or 180 rotation\r
+modes).\r
+\r
+"Fast renderer" enables faster rendering method, but it works only with some\r
+games (some other have serious glitches or even hang).\r
+\r
+"Accurate timing" is needed for some games to run (like Red Zone). It should\r
+be kept off for all other games, because it slows emulation down. Some games\r
+also need this option for proper sound, so enable this if game has any\r
+glitches.\r
+\r
+"Accurate sprites" fixes sprite priority problems, for example if game\r
+character is in front of or behind some object it should not be, this option\r
+should fix it. This option does not work in "Fast renderer" mode.\r
+\r
+"Show FPS" shows game frames per second in format XX/YY, where XX is the\r
+number of frames shown per previous second, and YY is the number of frames\r
+emulated, but not necessarily shown. By calculating YY-XX you get the number\r
+of skipped frames per second.\r
+\r
+3. Sound settings:\r
+\r
+Sound emulation is very picky on CPU power (in most cases sound alone uses\r
+more CPU power than everything else altogether), but it is still possible to\r
+play some games. When using sound, the recommended display modes are "fit 0"\r
+and "fit 180", because these are the fastest ones. Also try "Alternative\r
+renderer", but it might cause graphical glitches. You must use auto frameskip\r
+when using sound, or else you will get stuttering sound. Also, it is\r
+recommended to exit all other non-vital apps (you can use SMan for this),\r
+disable bluetooth and any other devices your phone may have. I also noticed\r
+that simply connecting the phone battery charger strangely slows everything\r
+down.\r
+\r
+"Enable sound" tries to enable sound output on your device, but that alone is\r
+not enough to get sound. You need to enable the sound chips below:\r
+"Z80" is secondary CPU in genesis and is mostly used to control the other 2\r
+sound chips. So if you disable Z80, sound will be lost in most games, with\r
+some exceptions like Sonic1. It is possible to use Z80 for other things,\r
+some games do that and Z80 must be enabled to run them at all.\r
+\r
+"YM2612" is a fairly complex Frequency Modulation (FM) sound synthesis chip.\r
+It was the main sound output device in genesis and is horrible CPU hog when\r
+is tried to be emulated in software. Disabling it gives large speed\r
+improvement, but most of the sound is lost.\r
+\r
+"SN76496" is programmable sound generator (PSG) chip, used for various sound\r
+effects and music elements.\r
+\r
+Note: if you change sound settings AFTER loading a ROM, you may need to reset\r
+game to get sound. This is because most games initialize sound chips on\r
+startup, and this data is lost when sound chips are being enabled/disabled.\r
+\r
+4. Misc:\r
+\r
+"6 button pad" will enable 6 button gamepad emulation and will add additional\r
+X, Y, Z and MODE actions to key configuration.\r
+Note: if you enable this, games may detect that and use different button\r
+configuration, for example A ("high punch") will change to "low punch" in\r
+Mortal Kombat and you will need to bind X for "high punch".\r
+\r
+"gzip save states" enables gzip (similar to ordinary zip, but a little\r
+different) compression on your save states to save space. The compression\r
+ratio is 50-90%, so it's worth to enable this.\r
+\r
+"Use SRAM saves" option enables emulation of batery-backed save RAM some game\r
+cartridges had. RPG games used it alot, but there were some others too, like\r
+Sonic 3. If this is enabled, <ROMname>.srm files are generated when you exit\r
+the emulator or load another ROM. Format is compatible with other popular\r
+emulators (like Gens and Fusion).\r
+\r
+"Region" lets you set the region of emulated genesis machine.\r
+\r
+\r
+5. Frameskip:\r
+\r
+"Auto" option tries to run the game in it's original speed by skipping next\r
+ frame if the previous was rendered too slow.\r
+"0" displays every frame, thus game runs very slow, sound skips.\r
+"1" skips every other frame. Use this for a game which is smoother, but a bit\r
+ too slow (actually depends on display mode you use).\r
+"2" also makes the game smoother, but it will be too fast in most areas.\r
+"4","8" similar to above, but skips more frames and often becomes choppy.\r
