Re: RetroCheat Video Series (about once a week)

Posting on twitter with no followers has no advertising powers.

I made some non-gameplay videos to.

Who wants a tutorial on how to find cheat codes? If you mean making them, I'm a beginner and except for 2 videos, none of them were made by me.

Is this all the Address Math?

Not sure what to call this, but learned something new today. That for certain codes/hex or whatever, you can write an address based on math. Zero-Page Indexed This works just like absolute indexed, but the target address is limited to the first 0xFF bytes. The target address will wrap around and wil...

Re: I think I created my first Game Genie code (Sort of)

I'm thinking a simple "ctrl + F" in the hex editor would work in this case to find out if an address is ever called.

Re: I think I created my first Game Genie code (Sort of)

padding area?
how do you tell if something is padding or not?

Did you mean $0000 & $00FF as well?

Re: I think I created my first Game Genie code (Sort of)

Basically, you're saying I did it correct for "testing purposes".. there's no way to change the value without loading another address.. I mean for testing.
Would probably speed things up.

I think I created my first Game Genie code (Sort of)

VYSLYOET (B157 val: 7B cmp: E8) ZASUAPLA (B158 val: 86 cmp: 03) LENATXNY (867B val: 03 cmp: 3F) Trying to get the marble to go turbo speed once it moves fast enough... still working on that. What I managed to do though is change the LDA $03E8 (or E8 03 in the hex editor) to load 867B (7B 86). I want...

Re: Am I reading this right. (cracking away at marble madnes

E246.. if the value is above 0, ignore E248 & E24A, and run E24D (correct? #1)

^ so these lines won't run then?

Probably a bad dump.. and maybe there's many bad dumps of this game out there.

It's been a while since I touched this game, so not sure why I forced cheated through this game to get past the crashed levels.

oh, it deals with crashing you say. that might come in handy for "Bucky O Hare Nes". there's a level that hard crashes.. not sure if it's a bad rom or what (I got past it back then with disabling random addresses). good examples. but are you supposed to use "execute" & "read".. I get confused when w...

Breakpoint confusion (read, write, execute, and other...)

I understand a bit more, and managed to create a simple new gamegenie code for highspeed pinball. I been experimenting with different games, but one thing I'm confused about is "read breakpoints", "write break points", and "execute breakpoints" Sometimes I debug an address, and not sure which to use...
