This was pretty awesome, good job on your first game!

How did you do it? I know that I still have to fix some stuff, especially stuff regarding extra lives (getting to 69 points). The jizz freezing in the air must have been caused by the "spoogespeed" variable having a value of zero

That's not a sentence you get to read every day.

Really cool you put this together. I'm still working on learning some of the basic concepts.

Edit: How long did it take you to put this together?

I lost the count of how many days this took me But basically, I did a few crappy projects at first until I knew enough 6502 stuff to be able to make this game

This just screams for an Arkanoid....
Nice work

I'm surprised you haven't seen this! Yes it uses an arkanoid controller, he/his dad made one themselves to test it.

^Lol!

I couldn't tell ya how I did it, just kinda happened, but looks like it's fixed now!  Nice

How cool would it be to release this game in a box simular to the atari plastic box with lock!

Seriously, I hate programming the music. It's one thing I learned to do only recently, and I suck at it. Here's my crappy sound engine with the notes it's supposed to play...

(Those are indeed not the notes of the final game)
Right now, the sound engine only plays Square 1 stuff, and I'll still have to make it play the other channels. I already hate sound programming

That's why there are several existing music/sfx libraries for NES, such as

MUSE (I made this one): http://kkfos.aspekt.fi/projects/n...
FamiTone2: http://forums.nesdev.com/viewtopi...

...and also others like DragNSF (I don't think it ever had an official release).

Sound handling is one of those things which can be quite easily separated from the rest of the game code, which is why it's possible to provide libraries to handle it.

MUSE looks like an interesting program and it doesn't seem to be hard to use. I'll check it that weekend and I'll tell you if I have problems!

This is quite impressive for a first homebrew. Disgusting idea, but really fun gameplay, and a great port overall. I always thought there should be more Atari or classic games ported to the NES.



...speaking of which, did anyone ever made a port of Pong on the NES? I'd love to see that.

Only about a million people.

I just implemented MUSE into Beat 'em and Eat 'em, and it works like a charm! I can even pull off some DPCM with it! Thanks for that great program!

There's actually an official version for NES on the game Super Spy Hunter!

I'd love to see Yar's Revenge, but iirc someone had already ported that too.  I don't remember a playable ROM released for it though.

Back on topic, woohoo DPCM!

Sorry to disappoint you, but apparently, I spoke too soon. The game works fine on FCEUX, but there is an annoying glitch on it whenever I try to play it on NEStopia (Mac version) - The two whores move a few pixels right from time to time, and it only does so when MUSE is playing music. Oh well, I'm just plain sick of music programming so I might as well make this the final version, with the lack of music contributing to the Atari feel. That and the fact that I want to move on to another project... The sound engine is ready, but this stupid glitch is way too annoying (even though it only glitches that way on a mac... Not sure about other emulators (except FCEUX where it works fine) or real hardware.
I updated the first post with the version I'd call V. 1.0., and I might update it when I'll have the courage to program some music into it.
Also included beatem_musicproto, which is a prototype with music (A nice version of the Cheetahmen theme that was included with MUSE... With DPCM ) if you want to see it with music. Keep in mind that I'm not sure this will work on all formats (Without the moving whore glitch)

I can tell you what the glitch is about. On the real NTSC NES, controller reads can get corrupted when DPCM samples are playing. To get around this, you need to read the controller multiple times and to compare the results to find out whether some of them got corrupted. You should be fairly safe if you read them until you get two successive reads that match.

Nestopia emulates this behavior, FCEUX does not.

EDIT: And by the way, I think sound effects would be a nice touch in the game.

About the sound effects : The first download has them (beatem.nes), the second does not... YET

About the glitch: How do you this double controller read thing? Do you have an example so I can try it out? (I never dealt with DPCM before, and I only had to read the controller once )

Check out this post http://forums.nesdev.com/viewtopic.php?p=89796#p89796 (find others from search) for some tips.

LOL! I figured it out! DPCM-glitch gremlin be gone!
I never knew about a DPCM-related controller read glitch... The things you learn! Oh, and back to more music programming T_T

Any idea where can I find a good version? I couldn't find any.

I've played the crap out of Super Spy Hunter! It's amongst my favourite NES games... and yeah, I've played its Pong minigame... it's extremely hard, if not unbeatable. I wonder if the game could be hacked in order to turn its Pong minigame into a stand-alone game...

I believe Sly Dog Studios made a pretty good 1K pong game!

Update

So put it on a cart and take my damn money!
