Don't believe Pugsy !

I have not checked rigorously yet about format and values so that treat the above codes as WIP (I hope to move this therad to WIP forum).

But it has too mysterious codes.

Why do you use Write if Match ?
Because when other value is stored into an address, these codes may works wrong or even doesn't work.
In this case, use bit-mask instead of Write if Match, I think.

Code: Select all

:discoboy:00000000:F925:00000004:FFFFFFFF:Infinite Energy PL1:Protects you from collisons with nasties but does not protect against weapon fire which kills you straight away

"Energy" code is NOT invincibility so that why do you add the comment about collision ?

Explain, Aardy.
And please search a lack of baaic cheats, like Rapid Fire and Stage Selection code, Aardy.

Sorry? These cheats are not WIP...they work just fine with no side effects I could find. I took extra care in making sure that they conformed with the cheat file standards

They are not 'mysterious'. Is it because I'm a newbie I must be wrong? I meddled with bit-mask cheats but they won't work because the addresses get used for other things which cause bugs at the end of levels. Write If Match was the only way to get the cheat to work flawlessly. I suppose it could be done equally as well with ROM cheats , but I've yet to use the debugger in anger.

Energy was the best explanation of it, but as energy doesn't get displayed I added the comment to make it clear what efffect it has.

And please search a lack of baaic cheats, like Rapid Fire and Stage Selection code, Aardy.

I don't consider Rapid Fire a cheat, and anyway the Auto Fire cheat would give you the same effect. Didn't find the level address, so couldn't post a level selection cheat.

They look ok to me, couple of typos but otherwise fine. Bizarre having to use that cheat type but it looks to be the correct choice from watching the contents and as bit cheats they would indeed be buggy.

Anyway, thanks Arrdy - added!

Thanks Pugsy

Anyway, here's the cheats Mr Pong requested

Code: Select all

:discoboy:00090000:F88F:0000000C:00000001:Stage 4 Boss
:discoboy:00090000:F88F:0000000D:00000001:Stage 5-1
:discoboy:00090000:F88F:0000000E:00000001:Stage 5-2
:discoboy:00090000:F88F:0000000F:00000001:Stage 6-1

:discoboy:00090000:F88F:00000012:00000001:Stage 6-4
:discoboy:00090000:F88F:00000013:00000001:Last Boss
:discoboy:00000000:F00C:00000000:00000008:Rapid Fire PL1
:discoboy:00000000:F00D:00000000:00000008:Rapid Fire PL2

SP, don't be sad but I used the 'Write If Match' cheat type again not just because I can but because it's ideal for level cheats IMHO. I still can't see how Rapid Fire is classed as a proper cheat but I've used a BIT cheat on it to keep you happy.

- Life
Maximum "display" life is 0x05 (real value - 1) so that adjusted 0x07 to 0x06.

Can you understand, Aardy ?

- Energy
Aardy's comment is incorrect because "Energy" cheat NEVER protects you from "Collision".
It protects from "Death".

Can you understand, Aardy ?

- Rapid Fire
Aardy's "Auto Fire" is correctly "Rapid Fire".

Auto Fire : fired automatically WITHOUT pressing a fire button
Rapid Fire : fired automatically WITH pressing a fire button

We should distinguish both items because these are different.
Can you understand, Aardy ?

- Invincibility
Yes, Aardy's code is wrong. It is made with BIT.
If you have an invincibility (flicker), bit 2 and 7 is ON (= 0x84).
Bit 7 is automatically ON if bit 2 is ON though.
Therefore, you have to poke bit 2 to enable/disable.

Don't use "Write if Match" in this case.
Can you understand, Aardy ?

- Roll
Also Aardy's code is wrong. If you get the Roll item, bit 4 is ON (= 0x10).
Remember Aardy's code.

Code: Select all

:discoboy:62000000:0000:00000000:00000000:Roll Mode PL1
:discoboy:00090000:F068:00000094:00000084:Enabled
:discoboy:00090000:F068:00000084:00000094:Disabled

0x84 is in the invincibility so that the above code works correctly ONLY IF YOU HAVE THE FLICKER.
When you are "Normal" (= 0x01), it NEVER works because "Write if Match" doesn't poke the value due to unmatch.
Over and over again, this operation works if $F068 is only 0x84 (= invincibility) and NEVER works if 0x01 (= normal).

Don't use "Write if Match" in this case.
Can you understand, Aardy ?

- RAM Check
This game has RAM check at boot and all cheat code causes RAM error.
Fortunatery, the game program doesn't check ROM region.

No. Write if Match is wrong in this case. See the above explanation.

Many bit-mask type Rapid Fire has a problem on the name entry screen.
Is it without this problem ?
If you have, add the following commet. See other Rapid Fire code on the database.

Code: Select all

Turn it OFF on name entry screen
