(Artemis) Code Types

[misfire]

I don't really understand the problem with 8 and 16 bit tests; the D code type supports both. Please give me an example.

As for your "slide code", this is the same as Xploder's "mod code" in the good old PSX days. I'll keep it in mind. Thanks.

If we wanted to implement 32-bit conditionals, we'd have to do so with a different code type for each conditional, wouldn't we? For example, there would be a code type for greater than, less than, equal to, not equal to, greater than or equal to, less than or equal to, within a range, etc...

[misfire]

No, you can actually combine many D codes to do more sophisticated tests by setting @n to the right value.

Implemented code type 6 (pointer write) and added it to the list.

[Lazy Bastard]

So you can use, say, two 16-bit conditionals to achieve one 32-bit, eg:

D00802CC 08001234
D00802D0 07005678
200802CC 8C860000
200802D0 10C00033
200802D4 00050C02
200802D8 00C13021
200802DC 10000030
200802E0 A4C50000
100800BC 00000083

...and this would accomplish, "If 802CC contains the value 1234, AND 802D0 contains 5678, then do the remaining 7 lines"? (perhaps I should change the 8 in the first conditional to a 1...I'm not sure)

[misfire]

Your example is absolutely correct.

Ah. I didn't see the 0/1 in your D code type listing there when I first looked. You're good. With CB, there wasn't a distinction, it always loaded a 16-bit value from the address to compare with.

[misfire]

AFAIK, the 8-bit compare was introduced in CodeBreaker V7.

Now that the most important code types have been implemented, it's time for testing them thoroughly. I've written a simple test driver program which checks the basic functionality, and I'm sure we can fix remaining bugs when the cheat engine goes public next week.

The engine is now in feature freeze. No more new code types will be added until after release. On top of my to-do list are bungholio's extension for the 4 code type and Viper's mod code.

Comments on the code types are still welcome, of course.

[Lazy Bastard]

Cool; I'm looking forward to doing some testing.

I'll also be interested to see what format you're storing the code DB in. We were talking about it in IRC last night. LB said it was going to be plain text, which could be good. I have to wonder about the processing time needed to parse a large ASCII file though. I wouldn't expect you to miss a detail like that, but I thought I'd mention it. I'm fairly sure the GS Pro code list was compiled by the PC app and sent to the console as binary. Whatever the case, I bet your cheat engine will beat the shit out of CB and AR.
