Block Attack, new game

Recommended Posts

Man - I hate to say this because people are going to get mad.  But:

1 - Emulators exist than can handle EVERY upgrade imaginable, some not even existing in real life.

2 - Stereo machines have existed since 1984 IIRC, and PAL has since pre-1980.

 

There are many upgrades that don't get support for precisely this reason.  Please try to realize.  It's 2023 and technology has moved on.  If nobody wrote software for more modern Ataris, we could still have shit running via cassette on 8kB machines.

 

Every time someone bitches that a game doesn't run on a 4kB OS-A 400 with original membrane keyboard, a poor soul who has spent money on a VBXE upgrade will NEVER have hope of getting software that supports it.

There are many games with awesome stereo tunes.

A second Pokey would be a nice upgrade.

Otherwise, with SubCart you can have stereo/covox emulation without opening the machine.

Stereo is needed to make IRQ interrupts work independently of music, POKEY #1 (SFX, IRQ generator), POKEY #2 (music on four channels)

 

without STEREO, only sound effects are possible

 

Playfield is two sets of characters switched every row on DLI interrupt (without using WSYNC), vertical scroll

 

what is the IRQ for? to change the colors of the panel on the right side of the playing field regardless of DLI interruptions

 

IRQ interrupts will look different in NTSC, different in PAL

 

that's why these requirements (PAL, CPU6502-1.76, STEREO)
