Hi!

I'm making a hack of Mega Man 4.

I'm actually trying to load tile ine the PPU VRAM, and I'M succeding, by setting #$00 in $2001, and then writing my datas at 2006 and 2007.

But the problem, is when #$00 is in 2001, after a certain number of cycle, parts of my screen become black. How can I prevent this?

thx for your time

thx a lot!

so I get it, because I do it midframe, my screen turn black, so I have to do it during VBlank.

But to do it during VBlank, it makes a wait during the gameplay of my game...

I don't understand VBlank 100% percent... but is there a way to call it?

For example... I don't know if you know mega man 5.... but in this game, during gameplay, without loading time, tiles are update in the PPU.

and what I don't get is how I can do it if I have to wait for VBlank? can I provoke it?

thx again a lot for the answer, really helpful

first, here is a link to my hack

Click to see preview

I'll probably be good to finish all in my rom by myself except 2 thinks...

one of them is that I would need to load a line of tile in the ppu one shot in a MM4 hack...

someone knows how to do it? I think it has to do with chr rom, but I would only need one for every weapon. for all the other graphics, I don't care...


you can also give me your opinion about the hack

Its a good hack, but you really have alot of issues to work out.

1.work on a better management weapon system.
2.Take out the rush jet and the metal blade from the beginning level.
3.the weapons menu, if I press select on the menu by accident my rom and emulator crashes.
4.work on spacing out enemie locations, limit black megaman to 1 in the level.
If it dies it should not be able to respawn again, otherwise I and many others will abuse it for reganining health too easily.

There are some other things I noticed in your rom but I'll keep that to myself.
Other than that its a nice starter, one request make rush's armor blue, it would like nice for a change.







Hi! thx for the advice... here are my answers


1- what do you mean a better management weapon system? it's a MM weapon menu...
2-) it's because it's a show case, I though it would be clear to people
3-) yeah it's because select will allow you to use item, I didn't though about removing the bad code before the demo..
4-) spacing the enemiees, I though about it too... if other people comment on this I will consider it...
I want do you mean, if it dies it shouldn't respawn again? every enemies in MM always respawn... even the black MM from MM9...

and you can say your other comments, I,m welcome to critics, but as you see I may not agree with every one of them... for instance, Rush is red and will remain red

but thx anyway

Hi

I have a simple question.

I wanted to know if the normal lag of a ROM could be avoided by some emulator? For example, in MM3, in the start of the stage with the spark bot, there is a lot of lag if you have too much enemy. Is it possible with any emulator to run the game without lag? I Wonder because I want to do it with my rom... and I noticed how Rockman 4 MI doesn't lag considering all the things you have in the screen.

thanks

thx a lot for the reply Kuja, I hoped for a simple solution from the emulator (like unlimited sprite with nestopia)

sometime I think I should rewrite the whole engine code to faster it... probably that is what I'll end up doing one day

hi!

I have a simple question : I'm now analyzing the whole code of MM4, ans then I'd like to create a new rom from scratch, in which I could write my function in assembly (like with FCEUX). I wondered if such a program exists? and if so, I'd like to know if there is one which allows me to give name to function, so when I create the code, it would place my functions in banks I set previously, but to adress not predetermined, so I would be able to expand my code again if I need to...

thx!!

In Mega Man 5, graphics tiles can be loaded on a second. In Mega Man 3 also. However Mega Man 4 cannot. Is there a way to hack a Mega Man 4 ROM to do so and so it could also be modded into a Mega Man 5 cartridge?

I see... so the best would be to use MM5 or MM3 directly....

I used to hack Mega Man 4 but since it could not switch lots of graphics at a time, I chose to instead opt for MM5. Since MM5 present this advantage, I guess it has a disadvantage in consequence. But I cannot see : if I understand concepts correctly : http://datacrystal.romhacking.net/wiki/Mega_Man_V

It has mor chr_rom and even PGR_rom than MM4. So what is the catch?

Also can someone tell me what other game use the same cartdridge as MM5 if I'd like to flash my hack on real cartdrige?

Thanks a lot for this answer!! But what then explain that graphics can be switch in an instant in MM3 and MM5? I'm not sure I understand that point. The guess I could take is because MM5 has some space considered only graphics, it could load it instantly, where in MM4 for example, it would have to be "built", using scroll gfx, before loading it?

As a side question, I prefer MM3 like I talked to you, but I saw there would be some advantage with MM5 as MM3 had some glitches due to bad programming (being one of the first MMC3) (like stage select glitch)

thanks for all the help, really appreciated

Instead of ROM hacking. net and DataCrystal, are there good places to find datas for MM1-MM6? I'm doing enemies import from one game to another.

Especially Mega Man 6, I have barely nothing on it.

Hi,

I'm now hacking Mega Man 5. I worked a lot on Mega Man 4 Voyage, recoded new boss.

Now I want to recode a whole engine. I started to document it, but I could use existing datas if there are...

1-) I wondered if there was another place than datacrystal with datas about it?
2-) Or is there an expert for this game who extensively hacked it?
3-) Is there a place with a list of bugs for Mega Man 5? I saw videos on youtube, but is there a place reporting them in a list?

Exactly what I was looking for!!

Are there other hack than rock5easily that speeds up engine?

I will rewrite all engine.If you want, I can give you datas on fixes I make (I won't fix things I won't keep like weapons for example) but I'll fix general bugs of course.

Thanks a lot for the info!!



Edit: what is this bug?
- Fixed the possibility to skip most of the boss rush by sliding through the wall (at least I think I fixed it)
