ROM Hack Boktai Solar Sensor Patch Kit

[Prof. 9]

So i was checking the source and found out how to change the buttons on the boktai 1 but on boktai 2 and 3 works wrong, the sun changes when i press left or right and stops changing when i hold A+R, so is reversed
this is what im using in boktai 2

ldr r0,=30044E0h
ldrh r2,[r0] // r2 = BUTTON_HELD
ldrh r0,[r0,2h] // r0 = BUTTON_DOWN
mov r3,080h
lsl r3,r3,1h
add r3,r3,1h
and r2,r3
cmp r2,r3 // if R+A held
ldrh r2,[r1,2h]
beq @@sunwrite

what i wrote wrong?
thanks

Change the last line to bne @@sunwrite, it should work then.

Any solution for the EzIV problem?

 

[gordillo]

i tried it on SCDSTWO and it still doesnt work :/

 

[jramon]

Thanks Prof. 9
it works alright now

 

[MiguelGarcia]

Finally i can play Boktai 1 on my iOS device, thanks

 

[NANASHI89]

will it play on VBA GX?

 

[Prof. 9]

To people having problems saving/loading, does the problem happen with a clean, unpatched ROM too? If so, there's not much I can do about.

To people asking will it work on X... why not try it out and let us know?

It wasn't saving on clean either, but don't worry I got a fix!
It was simple too, I feel stupid for not knowing it.

(Copied from my help thread)
1) SRAM Patch in gbata
2) English translation patch
3) Select button Solar Sensor patch (Prof. 9)
(note, steps 4+5 are optional)
4) Name entry patch
5) Menu graphics patch
6) Use the EZ4Client to copy it on, save type EEPROM, save size 128kbits

EDIT: I didn't do step 4+5, and it worked fine.
After a lot of experimenting, I couldn't get them working. Maybe try using a save created with VBA.

I was playing boktai 1 patched an fond that the rising sun grenade fills the whole bar instead of only 4 squares and doesn't go down when in ends
later checked the other games and happens the same with the magic rising sun in 2 and the django transformation in 3
I used clean roms and the patches in the kit
anyway it doesn't matter much if does that.

I have tested a patched Boktai 2 on the VBA GX, it works, and there is an "option" in the middle of settings regarding time of day.

I call it "option" because you can't really change the time of day unless you change the time on your Wii.

 

[Prof. 9]

I've built a workaround for the Rising Sun issue in Boktai 1, will update once I have workarounds for the other Boktai games as well.

 

[Generation 16]

How are the workarounds going?

 

[Prof. 9]

How are the workarounds going?

On the back burner, kind of. You can play the games perfectly fine without them, by the way.

i find the L+R combo impractical, as is press L, a grenade gets fired every time, but R only pans the viewable area around
but how do i make a patch or a patched rom file out of the .asm file?

should i have made a new thread?

/edit
thanx to kode9's sources & armips, my boktai now changes sunlight with R+UP/DOWN
if anyone cares "0C0h" must be replaced by "040h"

Hey there!

Could you explain how to figure out the control scheme? For instance, “040h” made it as R + LEFT/RIGHT, not R + UP/DOWN like you said.

Prof. 9, this patch is awesome! Thank you also for providing the source!

the values C0h and 40h are not the final values used

for R+L: C0h = 192 = 3x 2^6
for R only: 40h = 64 = 2^6

but the values are then left shifted using "LSL r3,r3,2h", basically a multiply by 2, executed twice (2h!), so multiply by 4, then the values become
for R+L: C4h * 4 = 240h = 576 = 3x 2^8 = 2^8 + 2x 2^8 = 2^8 + 2^9
for R only: 40h * 4 = 100 = 256 = 2^8

2^8 is the value for R, as the bit position 8 is used for R
2^9 is the value for L, as the bit position 9 is used for L

I recently jailbroke my ipod touch and I wanted to play boktai because everyone says its a great game and I also remember the crossover from megaman battle network 4.
I patched the rom and it works but I have to pause the game and use the key combo for the sun to come up and it only stays for a few seconds. I don't have enough sun to get past the first castle. Am I simply doing the key combo wrong?
Some clarification on what exactly you need to do (what buttons to hold and what to only press) would be great.

Also if someone is willing to show the code to change the boktai one patch so its R+A instead of L+R that would be awesome too.

Thanks Prof. 9 for all the hard work!

 

[Prof. 9]

Some things that could be going wrong:
- You didn't apply the correct patch (make sure the region is correct);
- The ROM was already solar sensor-patched (try the Clean+Patch patches, or find a clean, unpatched ROM);
- The emulator uses its own hacks to fake the sunlight level, which clashes with the hack (see if you can turn that off, or try a different emulator).

 

[bookdragon143]

I used the u patch so that isn't the problem (is the beta any better?).
And I used the clean+patch patch so that's done. I tried another emulator and I couldn't get it to work at all.

There's an error with the Filetrip downloader - I'll try again tomorrow as well, but as of today, the downloader that I downloaded goes anywhere from 50 - 70 percent completion (despite the desired file not even partially downloading), and then gives me an error after some idle time.

"Message from webpage

? There appears to be a network download problem. Try again?"

I know for a fact that I have a working internet connection, and FileTrip still works for me. Results are the same with firewall disabled and enabed. There is no antivirus.

I'm not sure if it can be solved but thank you for your time!
