New Homebrew: Robo-Ninja Climb

[gauauu]

Robo-Ninja Climb is a new homebrew game I just ported to Dreamcast. It's a simple action game, guiding Robo-Ninja up through a series of jumps dodging spikes.



I've previously made versions of the game for NES and Atari 2600, and this version uses the NES codebase as a starting point. This is my first Dreamcast homebrew, so I was pretty excited to see my game running on the system!

Let me know if you have comments or feedback!

Nice to see another dreamcast hombrew game.
The screenshot of the game, looks nice dude. Cool!

I have a few questions....
What game engine did you use, to make the dreamcast version of this game?
Or did you write your own code and game engine, to make it playable on dreamcast?

Also, great work gauauu!

Thanks! Let me know if you have trouble with it. It's my first DC game, so it's possible I've missed something.

I'm using Kallistios. Beyond that, it's just my own code. All the game logic code I just reused from my NES version, but replaced all the I/O bits with Dreamcast-specific code.

do not use RAMDRIVE for storage of big files, in the future you will feel the shortage of RAM
place files to CD

Is that the same as a ROMDISK? I figured I was probably better off eventually learning how to move my files out of that and into the proper disc filesystem, but didn't bother for now since everything fit. Do you happen to know of any good examples or documentation about the best way to do so? (all the KOS examples that I looked at used the ROMDISK)

example
sfx_powerup = snd_sfx_load("/rd/audio/powerup.wav");
replace to
sfx_powerup = snd_sfx_load("/cd/audio/powerup.wav");

in root directory your CD create folder audio and put powerup.wav

all simple

small trick

main.c

Code: Select all

#include <kos/thread.h>

maple_device_t *jump_pack = NULL;

static const char vmu_icon[] = 
{

/* font data */
extern char wfont[];

main.c

Code: Select all

int main(void) {

//	dbgio_dev_select("fb");
//	dbgio_enable();

	jump_pack = maple_enum_type(0, MAPLE_FUNC_PURUPURU);
	
	vmu_set_icon(vmu_icon);

	pvr_init_defaults();

mc.c

Code: Select all

extern void start(void);
extern maple_device_t *jump_pack;
void mc_dead(void) {

	if (mc_fadedTimer > 0) {
		return;
	}


	sfx_playSound(SFX_HIT);
	
	if (jump_pack)
	{
		static purupuru_effect_t effect;
		
		effect.duration = 0XFF;
		effect.effect2 = PURUPURU_EFFECT2_UINTENSITY(1);
		effect.effect1 = PURUPURU_EFFECT1_INTENSITY(7);
		effect.special = PURUPURU_SPECIAL_MOTOR1;
		
		purupuru_rumble(jump_pack, &effect);
		thd_sleep(20);
		purupuru_rumble(jump_pack, &effect);
		thd_sleep(20);
		purupuru_rumble(jump_pack, &effect);
	}

	if (mc_health > 0) {

now game support VMU LCD and PURUPURU (vibropack)

Cool, thanks for the advice, I'll take a look at adding that!
