Hi everybody, I made a patch to fix the speed of NGE Nibbles, but it does not come with a makefile: Instead, it comes with a RHIDE (DJGPP C/C++ IDE) config file to compile it with the DJGPP C++ compiler, also making assumptions about the source path.
Does anybody use RHIDE already and would be willing to make a new binary for me? Rugxulo? Toolchain: http://delorie.com/djgpp/zip-picker.html The patch applies to the SOURCE directory of the ZIP linked in our 1.3rc4 inventory list, after recursively copying NGE_NIBB to NGEPATCH: http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/repositories/1.3/pkg-html/nge_nibb.html Note that NGE Nibbles originally used mixed case file names. Somebody has changed this to all uppercase in the ZIP, so you should probably compile with LFN *disabled* in DOS. Thank you in advance :-) Regards, Eric diff -Naur NGE_NIBB/NGENGINE/VGA256.CPP NGEPATCH/NGENGINE/VGA256.CPP --- NGE_NIBB/NGENGINE/VGA256.CPP 2021-03-18 19:19:13.000000000 +0100 +++ NGEPATCH/NGENGINE/VGA256.CPP 2021-06-12 14:15:13.642979808 +0200 @@ -65,9 +65,14 @@ //--------------------------------------------------------------------------- void WaitForRetrace() { - char out=inportb(0x3da); + char out=inportb(0x3da); // color EGA/VGA input status 1 register - while(!(out&0x8)) { + // for VSYNC paced game: if retrace ongoing, wait for retrace end first + while(out & 0x8) { // while VGA vertical retrace in progress + out=inportb(0x3da); + } + + while(!(out & 0x8)) { // while VGA vertical retrace not yet in progress out=inportb(0x3da); } diff -Naur NGE_NIBB/NIBBLES/BODY.CPP NGEPATCH/NIBBLES/BODY.CPP --- NGE_NIBB/NIBBLES/BODY.CPP 2021-03-18 19:19:13.000000000 +0100 +++ NGEPATCH/NIBBLES/BODY.CPP 2021-06-12 14:00:30.632513438 +0200 @@ -320,7 +320,7 @@ if(t==0) { y0=y; x0=x; } - /*sequenza di morte 1*/ + /* death sequence 1 */ y=(int)(y0+0.4/mass*(t*t)); diff -Naur NGE_NIBB/NIBBLES/INTRO.CPP NGEPATCH/NIBBLES/INTRO.CPP --- NGE_NIBB/NIBBLES/INTRO.CPP 2021-03-18 19:19:13.000000000 +0100 +++ NGEPATCH/NIBBLES/INTRO.CPP 2021-06-12 14:05:35.188627836 +0200 @@ -73,30 +73,30 @@ unsigned char flipRed,flipGreen,flipBlue; bool flip=false,morph_1=false,morph_2=true; -int flipCol_1=48; -int flipCol_2=48; -int delta_t=60000; +int flipCol_1 = 48; +int flipCol_2 = 48; +int delta_t = 3 * FADEDELAY; // will be ignored if flip is true int c=0; LoadPalette(NULL,&palFX[0]); SetPalette(&palFX[0]); - /*ptrCalisto->GotoXY(100,165); + /* ptrCalisto->GotoXY(100,165); ptrCalisto->Print("press ENTER key...",ptrLogo->PtrSprite); */ DBuffer->ClearBufPat(ptrLogo->PtrSprite); DBuffer->Flip(); - while(c!=7181) { + while(c!=7181) { // 0x1c0d, ENTER if(kbhit()) c=bioskey(0); - if(c==283) return EXIT_FROM_LOGO; + if(c==283) return EXIT_FROM_LOGO; // 0x011b, ESCAPE if(!flip) - flip=FadingFX(&pal[0],&palFX[0],FADING_INTRO); + flip=FadingFX(&pal[0],&palFX[0],FADING_INTRO); // fade palette data if(flip) { @@ -176,7 +176,7 @@ WaitForRetrace(); SetPalette(&palFX[0]); - usleep(60000); + usleep(3 * FADEDELAY); }; @@ -186,7 +186,7 @@ WaitForRetrace(); SetPalette(&palFX[0]); - usleep(60000); + usleep(3 * FADEDELAY); }; diff -Naur NGE_NIBB/NIBBLES/INTRO.H NGEPATCH/NIBBLES/INTRO.H --- NGE_NIBB/NIBBLES/INTRO.H 2021-03-18 19:19:13.000000000 +0100 +++ NGEPATCH/NIBBLES/INTRO.H 2021-06-12 14:07:53.806090496 +0200 @@ -26,6 +26,10 @@ #include "DblBuf.h" #define EXIT_FROM_LOGO 1 + +// Palette fade delay in microseconds, was 20000 in MAIN, 3 * that in INTRO +#define FADEDELAY 10000 + //--------------------------------------------------------------------------- extern int Intro(DblBuf *DBuffer,unsigned char *scr); //--------------------------------------------------------------------------- diff -Naur NGE_NIBB/NIBBLES/MAIN.CPP NGEPATCH/NIBBLES/MAIN.CPP --- NGE_NIBB/NIBBLES/MAIN.CPP 2021-03-18 19:19:13.000000000 +0100 +++ NGEPATCH/NIBBLES/MAIN.CPP 2021-06-12 14:04:54.854597620 +0200 @@ -109,12 +109,12 @@ while(!FadingFX(&pal1[0],&palblack[0],FADING_INTRO)) { SetPalette(&palblack[0]); - usleep(20000); + usleep(FADEDELAY); } while(!FadingFX(NULL,&palblack[0],FADING_THE_END)) { SetPalette(&palblack[0]); - usleep(20000); + usleep(FADEDELAY); } memset(&palblack[0],0,768); @@ -126,7 +126,7 @@ while(!FadingFX(&pal1[0],&palblack[0],FADING_INTRO)) { SetPalette(&palblack[0]); - usleep(20000); + usleep(FADEDELAY); } memset(&palblack[0],0,768); @@ -153,12 +153,12 @@ while(!FadingFX(&pal1[0],&palblack[0],FADING_INTRO)) { SetPalette(&palblack[0]); - usleep(20000); + usleep(FADEDELAY); } while(!FadingFX(NULL,&palblack[0],FADING_THE_END)) { SetPalette(&palblack[0]); - usleep(20000); + usleep(FADEDELAY); } memset(&palblack[0],0,768); @@ -175,7 +175,7 @@ while(!FadingFX(&pal1[0],&palblack[0],FADING_INTRO)) { SetPalette(&palblack[0]); - usleep(20000); + usleep(FADEDELAY); } memset(&palblack[0],0,768); @@ -193,7 +193,7 @@ while(!FadingFX(NULL,&pal1[0],FADING_THE_END)) { SetPalette(&pal1[0]); - usleep(20000); + usleep(FADEDELAY); }
