Limitations and differences:
- Minimum hardware requirements for compiled programs:
* MSX1 machine (with ROM BIOS and ROM BASIC);
* 16kb of RAM for running as Cartridge without resources;
* 32kb of RAM for running as Cartridge with resources;
* 64kb of RAM for running with ExecROM (for 32kb ROMs) or ODO
(for 48kb ROMs) via disk driver or Caslink3/CASDuino/MSX2CAS
via cassete;
* 64kb Memory Mapper and/or MegaRAM for running with SofaRun;
* MegaROM compiled mode needs a Memory Mapper and/or MegaRAM with
at least the same size as the final ROM for running it in memory
with ExecROM (note: not required for running as Konami SCC
Cartridge in emulators);
- Partial file support (OPEN "GRP:", PRINT #...);
- No dynamic arrays (REDIM);
- No variant data type (only string, integer and single);
- All variables has an unique data type (dont change in runtime);
- Variables are not initialized at startup (do it yourself);
- Default data type is single (use DEFINT A-Z to modify it to integer);
- CIRCLE tracing and aspect parameters not supported;
- SCREEN cassette speed, printertype and displaymode parameters not
supported;
- STOP works like END;
- CMD WRTSCR/CMD WRTCHR activate the tiled mode in screen 2, forcing text
mode coords;
- LOCATE/PRINT works in graphical mode (screen 2+) without use of
OPEN 'GRP:'. When in screen 2 tiled mode, it works similar as text
mode coords (faster output);
- PUT TILE , (x,y) - for tiled mode used with screens 0-2;
- COPY works only with graphical parameters (no files support) just
like: COPY (x0,y0)-(x1,y1) TO (x2,y2);
COPY ... TO / COPY TO ... is accepted
instead of COPY ... (try HEAP() as );
When in screen 2 tiled mode, it works with text mode coords;
- IDATA (integer data) and IREAD (integer read) works similar as DATA/READ
but use less ROM memory and its faster;
- BLOAD works only to load screen files. You need to inform a file
name as literal (no via variables) because it will be loaded into ROM
(it will activate MegaROM mode). Ex: BLOAD "file.sc5", S;
- RANDOMIZE is the same as RND(-TIME);
- FRE() return free RAM size only (doesnt accept parameters);
- HEAP() return first free RAM address;
- TILE(x,y) return character from position (screens mode 0-2);
- MSX() return current machine version (0: MSX1, 1: MSX2,
2: MSX2+, 3: MSXturboR);
- NTSC() return true to a NTSC (or PAL-M) machine and false to a PAL one;
- TURBO() return true to cpu turbo mode (R800 or 5.37mhz) or false
to standard mode (Z80/3.57mhz). Use with CMD TURBO...
- VDP() without parameters return VDP version (0: TMS9918A, 1: V9938,
2: V9958, x: VDP ID);
- MAKER() return the manufacturer ID [1:ASCII/Microsoft, 2:Canon, 3:Casio,
4:Fujitsu, 5:General, 6:Hitachi, 7:Kyocera, 8:Matsushita (Panasonic),
9:Mitsubishi, 10:NEC, 11:Nippon Gakki (Yamaha), 12:JVC, 13
hilips,
14ioneer, 15:Sanyo, 16:Sharp, 17:SONY, 18:Spectravideo, 19:Toshiba,
20:Mitsumi, 21:Telematica, 22:Gradiente, 23:Sharp Brazil,
24:GoldStar(LG), 25
aewoo, 26:Samsung,
212:1chipMSX/Zemmix Neo(KdL firmware)];
Works only in some MSX2 machines;
- RESOURCE(number) return resource start address (use with COPY);
- COLLISION() return if a sprite collided with another sprite;
- INKEY() is a alternative to INKEY$, but returning an integer instead;
- Spaces on your line code, REMs and blank lines not affect compiled code
size, but if your include it on your program it can help the compilation
process (not need for strip spaces from your code anymore);
- Resources total size are limited to 16kb (for FILE directive), and
when compiled generates 48kb ROMs thats can run as cartridge or in RAM
with SofaRUN or ODO loaders (ExecROM do not support this ROM size);
- Arkos Tracker 2 player use the minimalist binary file (AKM and AKX),
with songs composed to play at 50hz, exported at 0100 address, and must
be included as the first resource in the list (AKM as 1st and AKX as 2nd);
- PT3 player support is now deprecated, dont use it. Also, it cannot be
used in concurrence with Arkos Tracker 2 player too.

Sprite Collision Detection
<-1=no collision|collided sprite number> = COLLISION( <-1=any sprite |
collider sprite number | &hCCSS> )
<-1=no collision|collided sprite number> = USR3( <-1=any sprite |
collider sprite number | &hCCSS> )
Examples
Beep if any sprite collided with each other:
SN# = COLLISION(-1)
IF SN# >= 0 THEN BEEP
Beep if any sprite collided with sprite 2:
SN# = COLLISION(2)
IF SN# >= 0 THEN BEEP
Beep if sprite 4 collided with sprite 5:
SN# = COLLISION(5)
IF SN# = 4 THEN BEEP
Beep if sprite 5 collided with sprite 4 (direct test):
SN# = COLLISION( &h0405 )
IF SN# >= 0 THEN BEEP
Beep if sprite 0 collided with sprite 1 (direct test):
SN# = COLLISION( &h0100 )
IF SN# >= 0 THEN BEEP
Notes
Sprites with same X and Y position are considered the same object, thus
there's no collision in this case.
