Clearned up.

• Converted all old codes to new ones.
• Deleted "Infinite Bombs" for thunderx. "Bomb" system is now thnderxa ONLY.
• Translated the codes for thunderx into thnderxb added on 0.104u1.
• Added Credit, Rapid Fire, Invincibility, Speed, Weapons and Stage Selection. But Invincibility (Flicker) is incomplete because you need to turn OFF at the end of the stage.

Thnderxa is the different game system from thunderx, thnderxb and thnderxj.

• Enabled "Bomb" instead of Extra Weapon.
• No Boomerang and Tail Laser (Only Normal Shot and Vulcan) and No Power-up, Speed-up.
• The address for Invincibility is different but the value is the same.
• Rapid Fire system is different. Thunderx has Semi-Rapid Fire (and the cheat makes it Full-Rapid Fire). But thnderxa doesn't have it.

Thanks, added.

Still working my way through your last cheat2.dat, sizewise I've now done about 60% of it, so still ontrack. I'm deleting everything from the cheat2.dat that have been added or have already included and I'm trying to put comments against cheats I haven't added for whatever reason.

:thnderxj:64004000:000x:00000000:00000000:Pre-Enable "Skip RAM/ROM Check"

This code prevents from RAM/ROM error after reset in turning a cheat code ON and enables quick boot. Using Pre-Enable, you need to change current value on the address field. Because it is variable depending on the position of "Skip" code.
For example : If you add after "Sound Test Timer Stop", set the value as 0x0011 (in thnderxa, 0x000D).

Pugsy HELP !
I'm trying to search a ROM code for Invincibility. But this game's program is too tricky to find collision check routine.

I'm not sure how I should add these cheats, I think it would be best to leave out the pre-enable cheat completely rather than adding it commented out with comments as the comments will only be valid as long as the cheats don't get rearranged or added to.

I'll take a ganders, looks quite a straightforward game though the Konami CPU I've never heard of...looks basically like 6809 on first glance.

[Pugsy]

Ok, I think these ROM cheats have no side-effects as far as I can tell. Just basically RTS'd where the sprite collison branch branches to on a collision.

Thanks but sorry my missleading information and you liar. Because your posted code have found already by myself. And this code is NOT the collision check avoidance. It avoids the routine of "death" after collision. Therefore if you turn off after a collision with an object, the player ship are suddenly broken !

I'm trying to search where a value is stored into $5810 if collide. But I have not find yet.

Pugsy, a lot of your "Invincibility" ROM codes are mostly NOT "collision avoidance" BUT "death avoidance". I find your job unsatisfactory. Therefore I have fixed these codes and re-added into my cheat database. I hope "complete" Invincibility and PLEASE DON'T ADDED "INCOMPLETE" ONES INTO OFFICIAL CHEAT.DAT !

[Pugsy]

Thanks but sorry my missleading information and you liar. Because your posted code have found already by myself.

I prefer not to be called a liar thank you, I have simply RTS'd the final branch in the sprite collision detection chain...ok it's not at the start of it. I didn't notice that when the cheat was turned OFF you died if you'd had a collision at all - but a comment in such cases would be fine.

I'm trying to search where a value is stored into $5810 if collide. But I have not find yet.

You'd be better looking at when 4980 is changed rather than 5810 as 4980 changes before 5810 and 5810 is filled with the data from 4980 by the code at $DC61.

Well that's why they are called 'Invincibility', death avoidance is a pretty good definition of Invincibility which means 'cannot die'. Collison avoidance would properly be called 'No Sprite Collision' it's just that it's generally also called 'Invincibility' because that's the effect it has.

I grant that dieing when the cheat is turned OFF is a bad thing though and I'm sorry I didn't spot it. And most of my cheats are 'death avoidance' rather than 'collision avoidance' because from past experience you need to be able to let good (powerups etc) collisions happen and stop bad collisions happening, this often means you have to kill several bad branches (and hope you haven't missed) and let all the good branches through. However if you just kill the death routine you can be sure that you've only killed the bad effects. Some of the invincibility cheats from the past had side effects with the sound effects that I never spotted because the driver at that time had no sound or because my speakers were off (I find it easier to think with no sound to distract) and for them I'm sorry. But I still hold the view that 'death avoidance' is a good way of searching for invincibility due to the unique branches it will take...it's also quite quick to find. In some cases though no sprite collision is the only way to find bug-free 'Invincibility' and in those cases I do go down that route.

And I don't see this cheat as INCOMPLETE, it does exactly what it says on the tin but I will add a comment that you will die when you turn the cheat off. I will have a look tonight though for the sprite collision based Invincibility, I've got to go to work in a few minutes and have only got a few minutes to play:-

Code: Select all

:thunderx:20900000:DE35:00005810:FFFFFFFF:No Sprite to Sprite Collision

This doesn't take care of background collisons though, but I think it's probably closer to what YOU want. If you haven't cracked it by tonight I'll will sort out the rest of the cheat..

OK, I said more than I should have. But you might keep that I want always more perfect Invincibility which is based on "Collision Check Avoidance" and hope to add a comment in case that "Death Avoidance" style causes a problem in mind.

BTW I have finally found complete Invincibility with ROM hack. It's VERY hard to search because $5800-$5FFF is banked RAM. This is no death when turn OFF and no killing an enemy when collied (another reason of disliked "Death Avoidance" type is that an enemy is broken after collision).
