Hi,

As a small challange I wanted to see if I could add music to games written with ADG by Jonathan Caudwell. ADG games usually take around 30k of memory starting from around 32000 so this leaves no room for music and playback.

My idea was that I would swap in bank 4 (@49152) and set up my music and then an IM routine at 25500. The IM routine swaps to bank 4, plays a frame of music and swaps the bank back to 0 and allows the game to continue. Here's the code I came up with (the music routine and data have been compressed with zx7 to take up less space)

An working example can be seen here with : http://torinak.com/qaop#128#l=http://zxbasic.uk/uploads/monty_tls.z80

I want to use ZXB "as Assembler only". So no single BASIC statement will be used.

E.g. I just want to assemble this:

ASM
ORG 50000
RET
END ASM

and after compiling this should result in just a .BIN or .TAP-File which contains the single $C9 mcode ($C9=201 dez for RET) and is in memory from adress 50000 dez.

Is there a simple way for doing this?

Hi again,

This time I try and create realistic pitch based vu meters. I noticed while doing this there isn't an inbuilt feature to ensure things stay nicely synced, I find PAUSE to blunt so used a MC routine that return false if not enough frames had passed or true if it was time for an update.

Music is converted from the Megadrive, music is on interrupts, uses Putchars for the octopus, some bits compressed with zx7.

Source included.

Hi,

in my project I use a lot of memory, indeed I use all the banks of RAM available. But my main code has grown beyond the 49151 position and now I have a serious problem by switching pages of RAM: ZXbasic stores some vitality data in the end of the generated code, like ZXBASIC_USER_DATA, so if the label overcome 49152, I can't switch pages without risky consequences

My question is, it's posible to move/relocate these labels to another area more secure?
Of course I could do it manuallyby editing the .asm generated but I hope that exists an easy way to avoid this.

Hello,

I've noticed that somthing that is possible is Sinclair Basic doesn't seem possible in Boriel....

eg:

Sinclair Basic

10 LET x=0
20 LET x=x+1-(50 AND x=50)
30 PRINT AT 0,0;x,
40 GOTO 20

As you can see x=x+1 will increment minus 0 unless x=50 then it will subtract 50. Great for loops and counters. In ZXB I am having to expand this into IF THEN statements.

x=0
x=x+1
myloop:
IF x=50 THEN
x=0
END IF
Print at 0,0;x,
GOTO myloop

Hi,

I´m missing the IN function in ZX BASIC (as it was in Original Sinclair ZX Spectrum BASIC).

Would like to use it as described here:

Must I use some machine code emulate?
If so, can someone please post me an example?

Regards,

Luzie

Another little play around.

EDIT- oh it was because I needed 1.3.0

I was using 1.2.9 so problem solved!
