About this game

fMSX is an MSX home computer emulator. It runs MSX, MSX2, and MSX2+ games and other software on your Android phone or tablet. Play MSX games with Bluetooth gamepads, Xperia gaming buttons, Moga gamepads, or iCade joysticks. Save gameplay at any time and restart once you get killed. Record MSX music to MIDI files and use them as ringtones. Play with friends over WiFi or Internet, using NetPlay. Play on a 55" GoogleTV screen, using your remote controller or USB joystick.

* Optimized for Android devices using assembler and 3D hardware acceleration, and running MSX software at the fastest possible speed.
* Full screen portrait or landscape mode emulation, with options for simulating TV scanlines and fuzzy TV display.
* Loads ROMs (*.rom), disk images (*.dsk) and tape images (*.cas).
* Supports PSG, SCC, and FM-PAC (OPLL) MSX sound chips.
* Emulates joystick using touch screen, Bluetooth controllers, physical keyboard, or accelerometer.
* Emulates MSX mouse.
* Supports GoogleTV devices running Android 4.x (Jelly Bean), such as LG G2/G3.
* Supports Moga, iCade, Nyko PlayPad, and other Bluetooth and USB gamepads.
* Supports Xperia Play gaming buttons.
* Network play feature lets you play with other fMSX users over the network.
* State Exchange feature lets you swap saved MSX states with other users.

This is a free, limited version of fMSX that may show ads and nag you to buy the full version. For the full, ad-free version, get fMSX Deluxe. Or, you can buy any one of my other emulators and the fMSX ads will stop.

fMSX package itself does not contain any MSX programs. You should place your own MSX files onto the SD card before running fMSX.

Please, do not run any software you do not own with fMSX. The author cannot and will not tell you where to find free MSX games or other software.

Please, report any encountered problems here:

From the settings menu, input, assign joystick keys, clicking a "left button" gives me "press key once to assign ..." What and where ? There is nothing on screen (the joystick), to see what and how was changed or what to do, only a lock icon. Edit : To map the joystick you have to buy the full version. Developer, be precise and tell us better the differences between the free and the comercial version. Other things, are good. Edit : Thank you for the info.

You do not need the full version to map the joystick. I think you are simply mistaking "Assign Joystick Buttons" (used to assign physical joystick buttons) with "Edit Joystick Layout" (used to rearrange on-screen controls).

one issue is controller support has bad nearly 1 second input lag, no other games or emus has this problem, using ShieldTV and DS4 controllers. 2nd issue that search functionality is broken, especially when trying to search from NAS shared folder, I tried this on my shieldTV & very slow to generate results if hundreds of roms in a directory. 3rd issue, fmsx doesnt support selecting a ROM file from multiple in a single zip file like blueMSX does. It simply loads the first on it finds.

Well, I do not see any input lag on my ShieldTV with the stock gamepad, generic BT gamepad, or generic BT keyboard. So, your controller may be the cause. Searching through a large network folder is, obviously, going to be slow. As to multiple ROM files inside a ZIP, not supporting this is a conscious decision: just gzip your ROMs individually.

Fixed lots, freedom from the google chokehold. However the keyboard is off. Important commands like ' + do not work correctly. Thus impossible to load cassettes. If your $5 version loaded cassettes without run'cas-' every time it would be VERY worth it. Good job fixing the major problems. Works 75%.
