This is an implementation of a well known puzzle game in which the player has to create a tile with the value two to the power of eleven or 2048 on a playing field of four by four cells. Use the cursor keys, the joystick in port 1 or an SNES pad in the first socket to move the tiles in the cells in one of the directions up, down, left or right. When two equal tiles "collide" during that movement they merge to a tile with a value twice that of the original tiles. The game is won if a tile with the value two to the power of eleven is created in the playfield. Press F1 during the game to return to the start screen.
The release contains the file f256_2048.pgz which can be started by /- f256_2048.pgz
from the BASIC prompt if the file is stored on drive 0, i.e. the SD card in the F256's
card slot.
You will need 64tass, a python interpreter and GNU make to assemble the program from source.
Use make to build the software and make upload to assemble the software and upload it to your
machine using FnxMgr. FnxMgr should start the program after uploading it, but if that does not
work press the reset button. After the reset the program starts. You may have to change the port name
from /dev/ttyUSB0 to the value that fits your machine. The target pgz can be used to build a
PGZ file.
If you set the variable USE_SNES_PAD in main.asm to 0, then support for the SNES pad is turned off,
which has the advantage that the created binary runs in the emulator. If you call make dist the following
files will be created in the dist subfolder of this repo:
cart_2048.bina cartridge image which can be written to a flash expansion cartridge2048_01.bin-2048_04.binwhich can be written to onboard flash via FoenixMgrf256_2048.pgza binary which can be run from any drive viapexec
You will also find these binaries in the Release section of this repo. This software is relocatable in flash memory, i.e. it can be written to arbitrary consecutive blocks in onboard flash or a flash cartridge.
