Re: BASIC input buffer $0200 - $0258

Thanks for the warning, I am actually doing just that!

BASIC input buffer $0200 - $0258

This seems a fairly decent amount of space, could I use this in an ML program that was started with a BASIC stub without screwing anything up?

Re: missile command

I've seen clips of people playing Missile Command on the Atari 2600 using an Amiga mouse, would such a thing be possible on the Vic?

Re: WIP: ZEPTOPOLIS

The real answer to this is "zero page." Except for a few storage locations that need to be part of the saved game state, everything uses zero page. I think that's the best way to compress 6502 code without tricks. In rewriting Gravity Ball, I've noticed places where I can change the curre...

Re: Standardized 'libraries' for Assembly?

Yeah, I can't have too much in each one. For instance in the above joystick routine I could have added something to push the current contents of the Data Direction Registers onto the stack, set them, read the stick, then restore them. That would have added size and execution time and if the keyboard...

Re: Standardized 'libraries' for Assembly?

Here's an example. Program code for JoyStick.asm JoystickS1 = 37137 ; Set data direction registers at 37139 to 0 JoystickS2 = 37152 ; and 37154 to 127 before attempting to read joystick StickUp$ = 4 ; read these 4 values from JoystickS1 StickDown$ = 8 ; these bits are INVERSE. Bit with be 0 on read ...

Re: Famicom-music on VIC-20

That is epic! Any chance of getting some of the music from Solstice? A vic would probably explode attempting that... :P

Re: WIP: Siege

Also quite similar to Runic Chess, a minigame from Star Ocean 3. Love the idea, and the clever use of PETSCII for the vehicles.

Standardized 'libraries' for Assembly?

I had to scrap Gravity Ball and start over because I was running out of memory and my physics were janky as f***. I was using almost identical code in multiple areas to do the same jobs, the program was disjointed and hard to follow, and the code I had to look over was huge, over 1000 lines with lab...

Re: ZEPTOPOLIS

Ah, got that bassackwards.

Also realized that your city can be disconnected. Here I'm taking advantage of lakes by starting small communities around them. Although a house just burned down north of that center lake, they aren't going to like that next year...

Re: ZEPTOPOLIS

RetroArch for Android has a VICE core and supports all the functions that RetroArch provides, such as Save State. For Vic I would prefer a portrait screen layout with stick and button on the left and right. It defaults to a Playstation style control layout which is ridiculous for the Vic. Edit: Foun...

I didn't realize you could get away with so few windmills, I think I'm throwing way too many of those out there.

Re: ZEPTOPOLIS

Making enough profit to maintain the whole place is going to be tough, my dream of amassing enough of a fortune so I can launch myself into space on a phallic shaped rocket while everyone else languishes in poverty isn't going to happen, is it? I guess I'll just have to make sure my people have what...

Re: ZEPTOPOLIS

Gack, made the mistake of building a ton of houses at the start of the game, kinda pointless considering they don't fill up very fast.
