Aliensclash openbor shooter platform game UPDATE

Post#1 » Fri Jun 28, 2019 9:29 am

Hi,

This is a very cool, platform shooter using, the openbor engine the pc game ,is by.. BloodBane.. I have edited it.. And it's using the updated openbor engine i have been, working, This crashes on the offical old bordc port. I have improved ,hacked the memory management.. In this game you can jump on platform's shoot and there is, shooting end level boss fight's , Also 2 game's one platform shooter multi directional shooting, And a side scrolling shooter Muilt layer scrolling ..
This is running on Beta 3 HW from me of the dc port of the openbor engine Full source code to engine can be found in other topic, post
This is running true 640x480 fullscreen 16bit
===============================================================================================================================
-- This openbor dc port will run on NullDC emulator, Official last release did not
--Progress made
-- Faster GIF animation and FPS
-- Faster frame rate
-- Faster file loading
-- Now load's on NullDC emulation
-- Malloc Debug turned of in Kos toolchain - May save memory - for loading small files
-- Will not crash loading 32bit 16 bit sprite's - they are displayed in the wrong colour Save's memory
-- Full Opt- Speed compiler flag's

================================================================================================================================

need change BIOS reactivation code in KOS and OPENBOR source code

Original KOS cdrom.c

Code: Select all

/* Initialize: assume no threading issues */
int cdrom_init() {
    uint32 p;
    volatile uint32 *react = (uint32 *)0xa05f74e4,
                     *bios = (uint32 *)0xa0000000;

    /* Reactivate drive: send the BIOS size and then read each
       word across the bus so the controller can verify it. */
    *react = 0x1fffff;

    for(p = 0; p < 0x200000 / sizeof(bios[0]); p++) {
        (void)bios[p];
    }


patched KOS cdrom.c

Code: Select all

/* Initialize: assume no threading issues */
int cdrom_init() {
    uint32 p;
    volatile uint8 *bios = (uint32 *)0xa01fffff;

    (void) *bios;



Original OpenBOR gdrom.c

Code: Select all

/////////////////////////////////////////////////////////////////////////////
//
// Initialize gdrom system
// returns the starting LBA of the main data track
//
int gdrom_init(void) {
  int param[4];
  int i, j;
  int first, last, track;
  int probable_lba = -1;
  int probable2_lba = -1;
  int definite_lba = -1;

  // Reactivate GD-ROM drive
  *((volatile int*)0xA05F74E4) = 0x001FFFFF;
  for(i = 0; i<(0x200000/4); i++) {
    j += ((volatile int*)0xA0000000)[i];
  }


patched OpenBOR gdrom.c

Code: Select all

/////////////////////////////////////////////////////////////////////////////
//
// Initialize gdrom system
// returns the starting LBA of the main data track
//
int gdrom_init(void) {
  int param[4];
  int i, j;
  int first, last, track;
  int probable_lba = -1;
  int probable2_lba = -1;
  int definite_lba = -1;

  // Reactivate GD-ROM drive
   volatile uint8 *bios = (uint32 *)0xa01fffff;

    (void) *bios;
