Hello
This is my first game for Gigatron. It is a port 2048 game by Gabriele Cirulli.
Is very simple, you must collect 2048 tile. No score this time.
Arrow key - move the tiles
START - retstart game
Is avaible two version:
http://blabla.ppa.pl/ftp/usr/Phibrizzo/ ... 48_32k.gt1
http://blabla.ppa.pl/ftp/usr/Phibrizzo/ ... 48_64k.gt1
Both tested on DEVROM. Version 64k on ROM v5a too.
If someone want to see sources:
http://blabla.ppa.pl/ftp/usr/Phibrizzo/ ... 048src.lha
All is compiled on my own compiler.
Enjoy

Looks good and is fun to play! Congrats on creating your own assembler as well!
I had a quick look at the source code and it's neat and tidy. One quick area you can improve on though is on your CALL thunk, instead of using this:
Code: Select all
LDWI #32816
STW @J
CALL @J ; show tiles
You can shorten it to:
Code: Select all
LDWI #32816
CALL vAC ; show tiles, (vAC is the symbol for the 16bit vCPU accumulator).

"CALL vAC" has own opcode? Or it is notation shortening?

vAC is hardcoded to RAM address 0x0018-0x0019, LDWI for example loads a 16bit immediate value and stores it into these RAM addresses. In your assembler just setup a symbol, (e.g. vAC), that represents the RAM addresse 0x18 and then you can use it as I showed above.
CALL can use any zero page RAM address, e.g. CALL 0x18, which conceptually is CALL vAC.

This is great idea. Thanks for this tip. I must implemented to my compiler.

Thanks for a new game. Very nice. What is the difference between the 32k and 64k version?

What is the difference between the 32k and 64k version?
Only allocation for code.
In 32K code is allocated in first 32kB, in 64K above 32kB. I did my first test on emulator with 64kB and it was easer for me.
Data for graphics is allocated in the same palce.

Hello
This is latest version of the 2048 game.
What new:
- rebuild all graphics routinies. Now is faster.
- fix input handler.
This version is based on 32kB sources but this time game running only on 64kB Gigatrons.

Little update.
I did some optimizations and i found one stupid old bug in shifting routinie.
Now game is more responsible.
