Double Dragon was Technos's second largest series. Outside of Japan, Double Dragon is much more well known because more Double Dragon games were released outside of Japan. This table shows where "Nekketsu Kakutou Densetsu" fits into all the Kunio-kun games Technos Japan released on the Famicom. It also shows games in the series made exclusively for other game systems during the time. Kunio-kun games continued to be made for other systems up through 1996.

Now it actually works on a real NES with a 4-Score or NES Satellite. Playing with 4 players at the same time is pretty wild. Don't buy repro carts! They are expensive. They don't support bug fixes for patches because they can't be modified in the future. If they aren't built from scratch they destroy a real cart. Every time a donor cart is used to make a repro, it raises the scarcity and price of that real cart. If you still want to spend your money on a mulitple repro carts, instead of buying a single flash cart, buy them from a vendor who only makes carts from scratch with new boards, chips, and housings. ------------------------------- USING THE PATCH ------------------------------- (3)------------------------- Patching the ROM File ---------------------------- How to patch the ROM file: You need: 1) A NES file. The file needs to include the standard 16 byte iNES header followed by the program disk image data. With header, the ROM file is 262,160 bytes in size. The header should be as follows: 4E 45 53 1A 08 10 40 00 00 00 00 00 00 00 00 00 You must have a 16 byte header for this patch, but even if your header is wrong, this patch will fix it because it replaces the whole thing. So, if you have a file without a header, you can just insert 16 of any byte at the start of the file. I'm not telling you how to get the NES file, but once you do, call it "Nekketsu Fighting Legend.nes". Note, this can be the raw file OR it can be pre-patched with the "oRdErEDchaos" 0.95 translation patch released on October 18, 1998. 3) Patch File: DvD_Nekketsu_Fighting_Legend_revB.ips 4) An IPS patching program Remember to patch the file only AFTER it has a header. Recommended IPS patching program for IBM PC: Lunar IPS.exe by FuSoYa Recommended IPS patching program for Mac: UIPS by Lucas Newman Using Lunar IPS / UIPS: a) Double-click "Lunar IPS" / "UIPS" b) Click "Apply IPS Patch" / "Apply Patch" c) Choose "DvD_Nekketsu_Fighting_Legend_revB.ips" e) Choose "Nekketsu Fighting Legend.nes" (4)------------- Playing the Game on a Flash Cart or Emulator ---------------- All emulators and flash carts that can play the original Famicom file can play the translation. The 3rd and 4th player is supported by NES 4-Score or NES Satellite emulation and, thus, is not supported by Famicom 3rd or 4th player emulation. The PowerPak flash cart emulates it perfectly. Games designed for the original Famicom/NES hardware have one or two 16k program banks and one 8k character bank. Later, all games made for the NES used special mapper chips to expand the size of the addressable ROM beyond these limitations. Some even included RAM for the character bank, instead of ROM. Game file size: 8 x 16 kBytes of Program ROM 16 x 8 kBytes of Character ROM 256 kBytes = 262,144 Bytes + 16 Byte Header = 262,160 Bytes This game uses mapper 4, known as MMC3, which is a very common mapper made by Nintendo. It is one of Nintendo's more sophisticated mappers, but not the most sophisticated one. ----------------------- CONTROLLER LOCALIZATION DETAILS ----------------------- (5)------------------ Why DvD Chose to Translate THIS Game -------------------- The main reason I wanted to work on this game is that someone asked me to! I had just finished Twinbee 2, which I added the 3rd controller support to. I really enjoy fixing games so that they can be played on the real NES, so I said sure. (6)---------------- Why YOU Should Bother Playing THIS Game ------------------- If you have a NES Satellite or 4-Score and at least 3 controllers, you will finally have a new game you can play with them. Playing a 4 player brawler on the NES is not very common! Invest in a flash-cart and play this and many awesome translations. This game only supports 4 players in the Rumble mode. (7)---------------------- DvD's Rev A Hacking Comments ------------------------ I've been on a kick localizing Japanese games so that they can be run on North American hardware. When I was asked to hack this game, I thought, why not? I know how popular Kunio-kun games are and I'm sure there are people who still play this game today. I quickly finished the hack and tested it out on my NES with my PowerPak. Then I added my credits into the title screen. I made my patch work both with the original game and the "oRdErEDchaos" Riki Kunio patch. While doing that, for the latter, I restored Technos's copyright and restored the awesome looking Technos Japan logo back to the splash screen. But then, to release it. DvD Translations have never released a hack that wasn't a translation. I just didn't feel this was big enough to release on it's own, and I really spend a lot of time making ReadMe's and editing the website, which I didn't feel like doing. So I waited until I had something else to release with it. Wow, two years went by very fast... (8)---------------------- DvD's Rev B Hacking Comments ------------------------ So, a week goes by and then... When trying to submit the patch to RHDN, I had the website check the ROM I started with and it said unknown ROM... Oh crap. I found a clean copy and found 3 differenes. Damn. After lots of dumping and comparing, the following 3 things were wrong (all of these deal with compressed screen layouts): 1) A splash screen tile was wrong making a single pixel on the splash screen not be there, the one on the right of the - above the small TECHNOS's "O" 2) The compressed attribute of 00 that was written to the entire attribute table was changed from 0 to 10. But even worse, the entire [End] character for the compressed table was change to 10 so it had no end. Ouch. The Riki Kunio patch actually makes this mistake. I fix it here. 3) 3 random bytes in the middle of unused data after a compressed screen (9)---------------------------- Project Timeline ------------------------------ Apr 15 2018 - Project started Apr 16 2018 - Added 3rd and 4th player player support on a NES - Added credits to title screen to work with the original "Nekketsu Kakutou Densetsu" and oRdErEDchaos's "Riki Kunio" patch - Alpha tested 3rd and 4th player support on a NES Satellite Apr 26 2020 - Patch credits copyright updated to 2020 - ROM 4 player controller localization released along with Demonic Castle Dracula and Bomberman May 3 2020 - Project title changed from Nekketsu Fighting Legend to (4 Player) Nekketsu Fighting Legend - Bugs from wrong starting ROM and bug from Riki Kunio patch fixed (10)------------- Software & Hardware Used In This Translation ---------------- * Emulator FCEUX 2.2.2 (FCEUX 2.2.3 has too many problems) by zeromus, adelikat * Disassembler & Table Dumper Table Dumper Pro (version 18.03.25) by DvD * Hex Editor Beyond Compare 4.3.4 by Scooter Software * Tile Editor Tile Layer Pro 1.0 by Kent Hansen * Disassembled code manipulation, script editing, & ReadMe creation Notepad++ by Don Ho and the rest of the Notepad++ team * IPS Patch File Creator Lunar IPS by FuSoYa * Testing on a real NES PowerPak by retroUSB ------------------------------------------------------------------------------- 987654321098765432109876543210987654321 123456789012345678901234567890123456789
