  1. I worked on this a little last night and thought I had it fixed, but I just wasn't pounding the "< CLEAR" quickly and fast enough. So, it still crashes if you quickly start repeatedly pressing the "CLEAR" key on the Select Pony screen. So the code on the Select Pony screen isn't reading the keyboard at all, it is just reading the Joystick. The only other code running is the DLI that changes the colors of Playfield 4 and Player 3, every line (for the ponies mane/enemy). This DLI is very tight, as far as time goes, especially during game play with both scroll registers activated. So I am thinking maybe quickly pounding on a key, may be causing the DLI to crash??? (Well technically I have a VBI running too) Having said all that, I think this bug priority is very low. If the game crashes because someone repeatedly hits a key on the select screen, then stop doing that, use the joystick instead. I think the root cause of this issue is that it isn't clear that the only pony available when you start the game is Twilight. So people thinking there must be a way to select a character, starts hitting all the keys on the keyboard. In the original game, on the select screen it had padlocks for the unlocked characters, so the player could see that there were more characters but they aren't available. So I may look at a way to make it clearer that you have to unlock the other characters.
  2. I tested this on my 130XE and I could reproduce this error. Not sure what is actually causing it. I don't know about your experience, but just pressing the arrow keys wouldn't cause the computer to crash. However, quickly tapping the arrow keys would eventually cause the game to crash. However, I could not reproduce the bug in Altirra, which makes it more difficult to troubleshoot. The code on the select screen is not reading the keyboard in anyway, so I am not sure what would be causing this.
  3. There is a way to unlock all the ponies on the select screen 🤫. Maybe you have discovered it 🥳.
  4. Yeah that stare distance with the barriers is a little tricky, so about that. Fluttershy is a little overpowered otherwise, but she was OP in the original game as well. Though I tend to lose a bunch of lives with her on the last level where you have to fly under the spikes.
  5. Thanks...that also happens to be what machine I test on 😛
  6. Hmm...I need to test this on my Atari when I get home.
  7. The only pony available when you start the game is Twilight, and you unlock the others after you beat the game with the current pony. Beat it with Twilight you get Rainbow. Beat it with Dash you get Applejack, etc. If you have unlocked the ponies, you should be able to select the ponies using Left and Right on the joystick on the Pony Select screen. If you can't then this is definitely a bug, I need to look into. (Oh and as The_Doctor says above, you have to tap the joystick left or right, you can't hold it in the direction. )
  8. Pretty cool. It has that classic gameplay, where you keep wanting to try again.
  9. Updated to version 0.82 Rewrite of all the animation code from C to assembly. This has improved game performance quite a bit. After refactoring and optimizing the current project I have freed up some more memory. I plan on improving the background graphics and maybe adding some background music. If you run into any issues let me know. advponies.0.82.xex advponies.0.82.atr
  10. Updated to version 0.82 Another small update to this project. I finished rewriting all the player animation code from C to assembly. I have freed up some memory so I hope to improve the graphics and maybe add some background music. Kaz sent me a cool splash screen that I want to incorporate. I am also planning on adding more background graphics.

  12. Wow, this looks awesome. Galaga was one of my favorite games in the arcade.
  13. This is really good reading, there is a bunch of useful information here. Just started reading through this, and noticed a typo on page 11 (or maybe I am not familiar enough with the syntax). It reads: LDX #$F6 shift_loop: LDA array-$F7,Z STA array-$F6,Z INX BNE shift_loop Shouldn't it read? LDX #$F6 shift_loop: LDA array-$F7,X STA array-$F6,X INX BNE shift_loop
