The backspace issue: which is the key code for BS on the MC-1000 ? There are two ways to solve it, the easier one should be to re-map its declaration in the adv_a source itself. The <RUBOUT> key produces 127 (ASCII control character "DEL") in "BASIC mode", and 93 ("]")...

Stefano! I believe I have fixed the low volume problem in click-generated sound. Below are the changes that must be done: 1) In libsrc/games/games.inc, sndbit_mask should be 15 istead of 8: [?] IF FORmc1000 defc sndbit_port = 96 ; $60 = YM amplitude register defc sndbit_bit = 3 ; More significant bi...

Hello!!! Good to see the forums are up again. Stefano, I changed joystick.asm as I told you by e-mail and microman worked O.K. Here is a video of it running: http://www.youtube.com/watch?v=i1sAPT6IZ3U Here is the full listing of libsrc/games/mc1000/joystick.asm: ; Game device library for the CCE MC-...

Couldn't get a new cable yet. Electronics stores are out of my route to work and back home, and other more generic stores I have happened to visit didn't have it. :-( Meanwhile, tests will have to be made in MESS. (I.e., sound tests suspended until then). I have tested the clock program in MESS satu...

Yesterday my P2-P2 cable stopped working (disrupted?) and I couldn't do any more LOADing tests in the real MC-1000. I'll seek to buy a new one today.

Stefano, I tested {z88dk}/examples/sound/clicktest.c in my real MC-1000. I sent the recorded sound to you via e-mail. The volume doesn't seem to be low, but the sound produced is very noisy. :( I opened the file in a wave editor and, strangely, the wave generated switches among various volume values...

Can the real MC1000 load also the WAV generated with the FAST option now? Yes, both files LOADed and ran OK. :) My attempts to tune the keyboard were all made on {z88dk}/lib/mc1000_crt0.asm I think HEAD should not be automatically changed to $ff. It should be left to the programmer to decide if he ...

As for the "1-bit" sound routines, here's how they probably could be in MC-1000: .bit_open ;di ld a,$07 ; Select PSG's mixer register. out ($20),a ld a,$7f ; All channels "silent" ; (and MC-1000's specific settings ; for IOA [output] and IOB [input]). out ($60),a ret .bit_click ;...

Stefano, looking at some programs code, I found that there are compiler directives like: How do we get that for MC-1000? Where would be "__MC1000__" defined? Is it tacitally defined when we put "+mc1000" in the zcc command line?

Is there a 'frames' counter in the interrupt routines which could act as a timer ? No, the CPU receives no information about the video processor, and keeps no track of its activity. The periodic interruption at $0038 controls the timing for the music in games and for the SOUND instruction in BASIC....

getk() should just get the current key code or zero, without waiting for a keypress. fgetc_cons() should wait (it is meant for the normal text typing, here a buffered keyboard wuold fit perfectly). OK, getk() will use "SKEY?", and fgetc_cons() will use "KEY" then. When there wil...

I compiled Othello for TLOAD. Loaded OK, started OK, but the keyboard wasn't working well. That's no fault of z88dk. It's because TLOAD enters "game mode" (system variable HEAD [$0106] = $00). In game mode the keys are not translated exactly as in "terminal" mode. <ENTER> gives &...

From that thread, I used decfreak's patch, i.e., adding these 3 lines to the install-libs section of Makefile: mkdir -p $(prefix)/lib/z88dk/lib/config cp -R lib/config/* $(prefix)/lib/z88dk/lib/config/ find $(prefix)/lib/z88dk/lib/config -type f | xargs chmod 644 And then after the makes I just mana...

Trying to install z88dk into my MacBook with OS X Mountain Lion, I had the same "Can't open config file" as decfreak, and his "3-lines patch" worked for me.

Continuazione di conversazione previamente via e-mail: [?] Devo mettere online tutti i file, spero che stanotte vengano compilati correttamente da 'nightly'. Hai compilato e installato z88dk da l? ? Se si, allora spostati in {z88dk}/examples e scrivi: zcc +mc1000 -lndos -create-app -Cz--audio -oothe...
