Anybody here know how to make Game Genie codes?

I'm making a short little Castlevania III ROM hack where I'm just replacing all the levels up to the first boss. I would like to make it so that when the player kills the first boss and picks up the orb that the game just goes to the credits instead of the map screen after the health and score counting sequence completes. Anyone know how to make a game genie code I can patch into the ROM that will do this?

I've tinkered with a hex editor but I can't seem to find the spot in the code where the target destination for level switching is set. There are already Game Genie codes out there for going to the end/credits screen at will by pressing start so I know it can be done I just have to find a way to tie it to the boss orb specifically.

I've already successfully implemented Game Genie codes into the ROM that skip the title screen intro sequence, name screen, and opening cut-scene, so having a code that will end the game to the credits after the boss is defeated is the only thing left I need to make this a tidy little episode. Currently I have a code implemented that disables the timer so that when the boss orb is picked up the point counter goes up to infinity because time cannot count down and so the game stops and cannot proceed past the end of the boss fight, but this isn't an ideal way to end the game.

Any help/suggestions would be appreciated. Pic related is a screenshot of one of the new levels I'm making.

My approach as a noob who knows nothing about this would be to copy the goal orb that appears when you beat Dracula.

That's an interesting idea actually, just swap the orb itself, but I still have no idea how to do it. Anyone know if there a hex editor for dummies I could use that visualizes the data in a more comprehensible fashion? The hex editor in FCEUX seems to be for advanced users.

Have another screenshot btw.

I looked into this briefly and if you go to rom address 0x004167 and change the "08" to "0d", then the game will go to the end credits instead of the map screen.

Thank you Anon, I punched that into my hex editor and it worked perfectly.

>visualizes the data in a more comprehensible fashion?
Nope. The data the hex editor shows is just what the data is. Each game is gonna use the data however it does and there's no way to generalize it more than that. What you have to do is the hard work of working out what data is what, unless someone else has already done that and posted it on some place like the data crystal wiki. That's where I looked to find https://datacrystal.tcrf.net/wiki/Castlevania_III:_Dracula%27s_Curse/RAM_map and the entry:

$0018 System State
00 = Title; 02 = New Game; 03 = In-game Transition; 04 = In-Game;
05 = Game Over Transition; 06 = Game Over; 07 = Stage Select Debug;
08 = Map Screen; 09 = Prayer Scene; 0a = Name Entry; 0b = Password Entry;
0c = Epilogue; 0d = Credit Roll; 0e = Respawn; 0f = Sound Test Debug

Then I set a write breakpoint for that address which triggered after getting the orb and above the sta command that wrote the accumulator to the address, there was an lda command that loaded the value of 0x08 into the register.

A time-limited collectathon themed around sex.

While I do see technical and gameplay improvements in this new Till & Hat demo, I definitely don't like the new tiles for the trees, rocks and the color palette. Some pillow shading here and there too.
The old build was weird mechanically and there was some visual flaws (there was some tangents between the foreground platforms and the background, main character a little lame), but overall the art style was much more consistent.

Right now it feels like the game slapped different assets together without trying to make them coherent.

I do wish the dev finishes the game first though.

All valid points, but I do really appreciate how the villains are an overt communist stand to the point that they are wearing Adidas as well.
This dev seems to have a sense of humor so maybe they are all right.

NHL 94 is considered one of the best sports games of all time, and one of the top Genesis titles. it's good, not just as a "sports game" but as a game full-stop.

Was going to enter the SMS coding competition but my game had bugs causing it to not start property, probably would have taken a week to fix. My fault since I knew about the deadline since December.

I've been enjoying the ECW Born to be Wired mod for WWF No Mercy. Been in development for a while, but the open beta dropped a month ago.
