    I got the hello world to work fine

    the 3 f18a samples worked fine including the scrolling demo.

    the 2 games bunny & diamond compiled fine with sound

    mode1plecompress rom compiled and worked fine.

     

    the sprite simple and animated samples compiled but gave black screen

    the music and simple sound comiled but gave me black screen & no sound.

    the bitmap megacart sample comipled to 128kb displays the first image but won't doing anything else despite pressing left right buttons etc. also I had to correct the the graphic table names in the megacart.c file by adding gfx to the end of eech (    vdp_dan2vram (TILimage3gfx, chrgen); // characters) then it works. I'll play with it a bit more see if I can get the other 2 images to display.

     

    I copied the bin folder also inside the pvcollib to the root directory before compiling and that worked.  c:\colecodev

     

    Hi @digress

    You need to run the .bat file to install pvcollib in c:\colecodev (take a look at wiki for explanantions), I don't think you need to copy the bin folder :(

     

    Regarding the samples you tested, I updated them and now they worked. I pushed the updates on github (only some fix with enablenmi and gfx names) but not yet released a new version

    I'm waiting for new feature we are currently working on with @newcoleco

    I think some influence must have come from my lib, since I appear to have a comment in crtcol.s! 😎

     

     

    you're right and I don't think I credit you about that, my mistake :/.

    I updated readme.md with a link to your website :)

    Regarding EmulTwo, i will work on it again to add more Adam support and update some screens for programmers.

    @tursi also added a nice fix to the previous coleco libraries that was causing video corruption to happen as there was a interupt still happening even if you had the nmi_diabled which caused me continual headaches. I really don't know what he did but I would like to make sure that it was addressed.

     

    His fix has worked ever since in the old library from @newcoleco i've been using. It was discussed here. Looks like you previously seen it too.

     

     

    Yeah, I also manage some code about VDP corruption, and you have two functions you need to use to update VDP OUTSIDE of NMI routine :

    Quote

    vdp_blocknmi();

    and

    Quote

    vdp_releasenmi();

    thanks for your tests @digress, I will investigate the blacks screens. That's strange but I think it is because I did them a long time ago and I forgot regression tests because I use pvcollib for each game I make without any issue :( ...

    For all community information, @newcoleco is working a lot to port some of her games she did a long time ago to pvcollib to have more examples to help us using pvcollib :)

    She is also working with me to improve pvcollib and add some functions!

    The grep command is only to present you the size of CODE, DATA segments. It seems that you do not have it on your computer, I will add it to the minimal command package I zipped with the installation.

    It is strange that you need to add bin directory to your path, I do not have this issue with my Win XP virtual machine ...

    Thanks for your reply.

    The music driver works fine with my game Sir Ababol, the music renders really different from the mod file I used, but it is normal as the Coleco does not support samples. By the way, the result is great.

    Regarding sfx, I will use the regular player but I wanted to know how to handle them with VGM. Now, it's ok, thanks to you ;)

    For your information, I compiled the lib with sdcc 3.9 and it works fine.

    Thanks again for your great work @Tursi !

    Really nice work Tursi, but one thing I do not understand is how to make sfx in vgm format ?

    I can understand how to convert mod to vgm, but what about sfx ?

     

    Another point: I can't see source code of the vgm lib, we need to link with your .a file ?

    *EDIT* found it in \Players\libcolecovgm2, sorry to have not checked before

    I don't know computer enough to makefile or make a batch file.  ;)

    Hard for this old dog(me) to learn new tricks, even though I'm not in my 40s yet. ;)  I will look into it and have F18A material ready. :)

    You know, I'm 53 years old man :P :D !

    ok, it is faster, but is it a problem ? my goal is not to have the same speed but a nice game. You think it is not nice like that ?

    I'm surprised that people still need to compare instead of saying if they think the game is nice to play or not ...

    Please, could you give me where it can't be possible to "past the bad guys", with some screenshots for example, it will help me to understand. Regarding the grave (or bible), it seems ok for me,I will check again ...

    For your information, monsters and Sir Ababol are using the same frameskip  (1 frame), so I think it is now a good compromize for the game.

    Regarding monster speed, I managed it, don't worry, they move slower now ;).

     

    The other problem is not a ROM issue with monster, but a RAM issue. I will try to store monsters coordinates in VRAM , will see if I can have something ok...
