No love for noobs?

Hello all, I am working on my first homebrew game, and I need some help/suggestions. I would like to be able to bring up a gameover screen once the score rolls over to 999999 I would like to be able to bring up an end screen once the score rolls over to 999998 I would like to have additional enemies come once the score rolls over to a certain number The same for one powerup The powerup, I would like to be able to allow the sprite you control to fire horizantally along with straight up And lastly, music, sound effects I know I'm probably way over my head, but any suggestions would be a great help. Thanks. Oh, and I attached my bin file. And yes, Wind Squid from Classic Game Room... WindSquid0.1.bin

Honestly, im not experienced in this. Ill go with a 74ls04 if i can find it.

Sorry, I had a hard time finding a suitable eprom. Is this good? eeprom Also, which address lines are unused? And by inverter, did you mean a 7404 hex inverter?

Nope! See post #2 I got that, but what pins are the A12, CE, OE, and ground. I can't find a pinout. Also, what do you mean by "You'll also need to pull unused address lines to ground."

I mightve posted the wrong part. Its a 16k onsemi eeprom with .6 spacing. The chip and socket are fine, if a 16k is suitable, then I just need to know the pinout of the chip and the board. It's probably a 28c16 or similar, which is 16k bits not bytes. It's not big enough. %$#)^#$^&$#) %^$&$)%&$%&$Y^#$&^) I didn't order the part. So the minimum size is a 32 kilobit? I'll have to ask the man who burned the eeprom a question, because he burned an 8 kilobyte game on there... Anyhow, once I have the correct chip, do I need anything else or can I just use it as it is?

No! You'll need an inverter between address line A12 and the EPROM's Chip Enable CE (active low) signal. The EPROM's Output Enable OE signal should be connected to GND. You'll also need to pull unused address lines to ground or double up the binary image in the EPROM. OK. I have no clue what that means. If I could get a pinout that would help. What do you mean by "you'll also need to pull unused address lines to ground." And Inverter? Also, not knowing this beforehand, I burned an 8K ROM and used it on a 4K board not knowing it was a 4K board without the inverter and all of that. Is it still usable? If it helps, I've got this chip My link Thanks.

Hi all, I'm new to the forums, but I've been lurking for a while. I've got a copy of pitfall (4K PCB I assume) and an eeprom thats over 4k. I removed the chip and added a socket. If I burn a 4K game, say Halo 2600, would it function correctly? Thanks in advance.
