Post subject:  Star Evil and F-FF

Gonna post these a few days early in hopes that bugs will be caught before I submit them. I haven't tested them on real hardware. NTSC only.

Star Evil

A simple remake of the A52 game. I tried to make it faster paced and less glitchy, while still keeping some the original charm.

D-Pad: Move
A/B: Shoot
Start: Start Game
Image Image

F-FF

A basic racing game. Hit select on the menu to get 2p split screen.

D-Pad: Steer
B: Accelerate
A: Boost
Start: Start Game
Select: Enable second player (on menu)

Star Evil is interesting. I wonder how many people will miss it.
Edit: Beat it.

Star Evil looks promising. No bugs found at first glance.

I feel like I'm missing a lot of somethings. I can't evade or destroy the first blue square in Star Evil, and the game I get in F-FF is a lot more impressive than the preview image implies

Hint: the game has only begun when you think it is ...[]

FFF - I like the scanline effects.
Star Evil - As buggy as the original.

Edit to remove discussion about the car's drag redution mechanism.

Star Evil feels a bit postmodern.

I did find a genuine crash in it, too, but I have no idea how to talk about that without spoilering things.

Yeah, my first thought was "how can you even tell if it's a bug?" ;-)

Is the cheeseburger screen the real ending?

Yeah. I was running out of space so that's it.

I did manage to crash Star Evil. The program counter was around $4000.

Both games make me want to play them more. Good work.

Jeez. Running either game in a debugger, with "break on bad opcode" is like looking into the abyss.

Setting a breakpoint on execution in $0000-$7FFF shows it jumping to PC=$2007 ??

FCEUX's execution logger shows this:

That's the level loading code. It's probably trying to load an invalid level pointer.

What screen were you guys on? (you can PM me)

In this room, if you go through the right doors, and hug the lowest part if it (by pressing down + right as you go through) it will crash the game.
