Computer Space/Pong Reception


Kiwi

803 views

I'm pretty happy that it is getting good receptions. I'm also nervous about it too, since it is project that is going to be release into the public space. I'm going to make 100% sure that there no game breaking bug at launch. So far, no bugs and the game's stable. Eventually, I need to burn the game on EPROM somehow and it needs to be tested throughtly since the game uses byte_random for multiple of things. The star scrolling is position randomly when it reach the edge of the screen, the star plotting is random, UFO movement is random. newcoleco said that when the game is burned on EPROM, the system RAM is started up at random. The Ultimate SD cartridge set all RAM to 0. So that's something I need to test to see if there going to be abnormal behavior and write a random number generator to get around that.

 

As right now, I've wonder if Computer Space ends the game when UFO hit 7. I remember seeing a video of the arcade having time left on the counter. I have my version stops at 7, but the UFO can still continue scoring. I do need to replace the letters with the actual glitched numbers. Then put in invert flash when UFO was hit.

 

I'm going to try hard and focus on working on this game to completion, so I don't let anyone down.

I have it at the very first line of the code. The sound effects does work when set_snd_table(snd_table); uncommented.

void main(void){
//set_snd_table(snd_table);
disable_nmi();
screen_mode_2_text();

I think that was the reason the sound didn't before since I didn't know where to put set_snd_table at in the code. The 10 year birthday was missing the set_snd_table. Once I added that in, the music plays. I felt like a jerk after I figured that out. I did find an application that newcoleco made, CV note to help produce series of tone/noise. Computer Space sounds are pretty complicated. I did get the turn sound right. The bg space noise so-so. The player missile 3rd channel tone to go along with the bg space noise. Ship getting destroyed and UFO destroy sound I think are the only sounds left to make.
