Great work!

Here!

EDIT : URL above is now correct

There is another bug you can fix..

If you have legend boots and you buy the green armour in baraporo village, wonderboy behaves as if he is on ice or wearing ice skates, he slides about until you upgrade his armour.. An annoying bug...

HHHaaa! Someone who really plays the game instead of just collecting it!

Thanks for your bug reporting! I have few questions that might help me finding the cause:
Does this happen each time you do it?
Which version did you play?
What is exactly your equipment when it happens?
Does the game freeze?

I'll try to sort it out next week.

If anyone finds anything else, don't hesitate to post a report here!

Cheers.. yes I play it, its one of my faves. I can 1cc it, top score is 3.2million I think..

The version I play is an Engrish bootleg, it says for eg: "68 Gold" when I collect coins, the other Engrish bootleg would say "68 Gold Get".

Yeah, the bug happens every time. You will know there is a bug whereby the armour is available in a mixed up order and the legend armour can be achieved on the third upgrade for minimal expense before it (a total spend of 160 gold then the Legend armour becomes available). I will buy the Legend boots in round 2, followed by Light armour (60 gold, pink colour) in round 3, then Heavy armour (100 gold, green colour), and I always have the Light shield (40 gold, pink colour) as I only buy the cheapest one (upgrades have no difference other than colour).

So I have..

Legend boots
Heavy armour
Light shield
Broad sword
Scroll
Revival potion

..and Wonderboy behaves as if all surfaces are ice, just like he does on the ice stages. The ice skates effect disappears when the green armour is changed/upgraded. An annoying glitch as this the way I play for highscore. It's not a game finisher though as the Legend 540 Gold armour is available in the second stage of the next level, just make a couple of boss fights trickier than they should be!.

I caught it on video too, its in my 1cc video. You can see it happen, watch from 8mins.. it happens at 8.25 you can see the huge difference in the way Wonderboy handles!

Hi

I though you were playing one of the romsets I worked on. I haven't tested anything yet, but I though about it and here are some leads I'm gonna explore : all the bootlegs romsets (when I say bootleg, it doesn't include VC version) are base on the Japanese Old version of the game. Maybe the sliding bug you encountered was corrected in the "new" japanese version (with ep11031a file for IC90 instead of epr11031 file), and so "maybe" this was corrected on the VC version of the game.

Anyway, this bug is not due to the decryption process I spent time on, BUT if this bug has been corrected on the Japanese new romset, and not on "my" english romset (base on the VC game), It's possible to corrected it. On the contrary, if it's still on the Japanese "new" romset, I'm affraid I won't be able to do anything.

The coin glitch that gives 63-68 golds when getting hidden treasures occurs on every version of the game. This was not intentional, but finally the game is as it, and now it's part of it.

Sharky will tell you how much I love this game too!!!

Please can I get your roms

I had this working on a real board the day the vc roms were on the net

I played it
Noticed the gauntlet instead of the sword, gutted!
I noticed Sarad as well
Really want to play it with this all corrected
I can't quite finish the game but very close, have been saving it till I got my orig pcb with the new roms
I have a boot (engrish) but wanna play it for reals lol

Please show me the roms?
Are they on Porchy's site?
All I found there was 317.xxx
My pcb is 315.xxx
Confused?

Holy ****. Wonderboy in Monsterland is my favourite game!

I need to go back through and read this whole thread, but just had to say...holy ****!

(I will say one thing though - i kind of love the **** up translation. First time i played it and fell in love with it was in Cyprus in the late 80's, moved on to Master System version for my entire childhood, been rinsing a bootleg board recently and was hoping to get another...amazing game!)

Ok, just read everything.

Amazing work

"Gold get" is the version i know and love! I'll look forward to playing this version one day too.

Congratulations dude, great achievement!

Hello

I spend so much time on it that I'm glad some people appreciate my work

@paulcan69 : Number indicated on Porchy's website (317-0043 for WBML) is the reference of the modified Z80 (with the battery and the decryption program) that was first on your PCB before been unsuicided. Now it's removed, that's the reason why you can't find it.

@everyone : you can download the roms files at the last page of the download section here.
For those who are too lazy to seach, here are links (targets are files on Porchy's website)

link to the English version of WBML

There is a directory called 512k which contains files that you must use if your board has been modified to fit with 512k eprom (27c512) for IC90 and IC91. Those files work on bootleg PCB too. I also put 512kb IC92 file in case someone uses a bootleg PCB that requires 512kb ic92 file. For bootleg PCB, locations are called differently.

If you have a original PCB that has not been modified, just ignore "512kb" directory. On Porchy's website, I also provided files for Japanese versions (old and new version) that work with untouched PCBs (no need to change IC4/5/6 for Japanese version if you already have original eproms for those locations)

In any case, you'll have to burn mpatou.ic4 mpatou.ic5 and mpatou.ic6 on 27c256.

Well, even if you use the link I've provided before, take some time to visit Porchy's website, and eventually make a little donation (none of this money would come to my pocket)


EDIT : I forgot to say, do not use these files for commercial purpose!

Brilliant!!!

This is great news. Imagine a proper English version of this game becoming available after all those years, such a little known game as well.. astonishing that it happened! If someone predicted that ages ago they would have been laughed at- more chance of winning the lottery.

Excellent, thanks a lot for this nice work!

I have an original PCB with modified 512k EPROMs, what do i have to do to use the 256k ones again?
Just remove the wires they put on the two 512k EPROMs, to get it running again with new programmed 256k ones?

Also my PCB is lacking sound, any idea if this could be related with the modified 512k EPROMs?

It's not necessary to undo the modification if you don't want to, just use 512kb rom files that are in "512kb" directory of the archive.

Ok, i understand - but i want to get rid of these nasty wires...

Okay, in this case download this (from retroclinic), and do the modification described in the .txt file "backwardly" (there are some pictures to illustrate)

Are the patched roms bugfree yet or are there still known issues?

It has same bugs as the original japanese "new" romset, like money bug for exemple (that is considered part of the game now). I don't know how to fix it and I don't want to correct it.
If someone find a non-reported bug, just let me know.
