Atari Flashback Portable Question

Fri Feb 22, 2019 12:05 AM

Which version of the Atari Flashback Portable is better emulation wise the 2016, 2017 or 2018 version. I ask cause as far as games go I can easily add in the entire 2600 collection to the SD card so the built in games don't matter. I also plan on testing my homebrew on it, so if someone could post which versions of Stella are running on each version, it would help me with my decision on which one to get as well.

[POLL]Heroes & Shadows Game Type

Mon Dec 3, 2018 8:44 PM

Well with AtariVox+ support on hold, I am interested in knowing how you would like me to proceed. There are 2 types of game types I would like to use for my game. Read the descriptions below and vote on the poll on your favorite. The winner will be considered as a possibility for the game's new type.
In this genre type, you control the president via the keypad controller. You enter commands via the keypad buttons in the order you would like to execute them. After entering the desired commands you press another button and the commands are run in the order they are entered until they are all executed. Your goal is the reach the goal in the least amount of commands. You will be able to hear speech and save your high score via the AtariVox+ when available. The Atarivox+ is not necessary and would be optional. Having one would add additional features.
In this genre type, you take care of the president via feeding and training him(think Tamagotchi). Over time he will become stronger and fight the invading creatures. There is the possibility of having different carts with different creatures you can train. One thing I was thinking was having presidents fight each other via a special "tournament" cart. You will be able to hear speech and save your stats via the AtariVox+ when available. The Atarivox+ is not optional and not having it would make the game incompletable.

Can't get F8 Bankswitching Working

Mon Nov 19, 2018 9:06 PM



Trying to get F8 Bankswitching working after my cloud instance crashed. At the moment all I get is a black screen. If I remember correctly Bb with the 8k ROM option stores the code in Bank 0, and graphics and data in Bank 1 according to something i read. I am trying to accomplish the same effect. If anyone can help me it would be greatly appreciated.

[HELP]Movement Not Right

Wed Nov 14, 2018 6:07 PM

I am trying to get my "character" to bounce between the left and right parts of the screen. Here is the code I'm using:

First, the global equates:

LEFTBOUNDRY        equ                 #20
RIGHTBOUNDRY       equ                 #144

and then the actual code:

; pet movement code
   lda PetX                                                                    ; load pet x position into accumulator
   clc                                                                         ; clear carry flag
   adc PetVX                                                                   ; add the pet's velocity constant
   sta PetX                                                                    ; store pet's new x position
   cmp #LEFTBOUNDRY                                                            ; does it intersect the left boundry?
   bcs SkipReversePetDirection                                                 ; if not branch
   cmp #RIGHTBOUNDRY                                                           ; does it intersect the right boundry?
   bcc SkipReversePetDirection                                                 ; if not branch
   lda PetVX                                                                   ; load the pet's x velocity
   eor #$ff                                                                    ; negate it
   adc PetVX                                                                   ; add pet's current velocity
   sta PetVX                                                                   ; store the pet's new velocity

Playfield Error

Mon Nov 5, 2018 7:33 PM

I am trying to create a very simple playfield, however, for some reason, the playfield seems to come out incorrectly. First off the playfield color is wrong but, that's a fix for later. The issue is the playfield seems to be rotated, like the TV fell on its side :twisted: Here is what I mean:


Here's the latest version of my source code: https://www.dropbox....0-5-18.zip?dl=0
