There is a strange, occasional bug in Space Harrier where, once the HuCard is switched on the screen splits into four (aka N64 style). When you start the game in this weird mode the speed of the game is quadrupled. You can increase the chances of the bug appearing if you keep quickly switching off the HuCard then back on again. I had that that exact glitch happen in Power Gate once. I wonder how common this is. I've also seen it before, when the cartridge doesn't make proper contact. It's pretty rare (like I can't make it happen intentionally), and isn't specific to a game. Dave

I know that 4 screen thing also appears on older namcot pc engine games I think World Court Tennis was a case too.
EDIT
you use a code in the password system
gamefaqs: Four-way split screen - Enter the cone symbol in all spaces

Dragon Slayer IIIf you run this on a system with memory at bank $49 (for example, special hardware or an emulator with this page mapped as RAM), the opening cinemas will run, but the game will stop functioning when the actual game starts (main character in bed, about to be greeted with "Ohayou"). This is caused by the game doing a mistaken check for RAM in bank $4C (it reads location $FFE5, which is a JMP instruction), and it then enables a debugging callback that crashes when executed on consumer hardware (or an emulator). This is presumably left over from some proprietary development hardware that the authors used. Anyway ... the bug surfaces when you're running my System Card hack for the Turbo Everdrive 2, or when you're running my modified version of Mednafen with all the extra RAM that my mod provides. I have a new patch ready for the TED2 System Card that fixes the bug, and I'm going to modify my Mednafen patches to provide only 448KB of RAM in order to avoid triggering the bug.

Cool, once that's available, I'll amend this in the list.
I think you mentioned that Tenshi No Uta has some sort of a problem with American system cards... that's also the kind of thing I'm also looking to document here. Any details you can provide would be appreciated.
Dave

War of the Dead: Mine (used) didn't come with a card. But if you can find such a card, I'd like to get a translation put up. Let me know if you still need it, my copy has one and I can snap a picture of it.

I'm still not convinced about the replacement version existing, but at least I've seen more than one person talk about it.
The guy from Redump probably still has the disc he used to upload the revision to the database, and there's a ISO of it floating around.

I don't understand a word of it but there are too many italicized exclamation marks on the text for it to be a "sorry for these bugs" message. Are they actually trying to sell those bugs as features? lmao.

Translation:
In support of Certain Victory, 5-point card (more idiomatically, "This card contains 5 points to help you succeed") (Please read before starting to play !)
Point #1: Remember that earning experience points is not as important as talking with people ! While this game has many elements of an adventure game, increasing your experience points by fighting is not a shortcut to finishing the game. Please be patient, listen to peoples' responses in conversations, and solve puzzles. Occasionally, it may be necessary to run away from enemies.
Point #2: If you recklessly fight too much, Lila's PF points will vanish ! And die ! The maximum value of Lila's experience points is 9999. If this is exceeded, Lila's PF value will vanish and become 0. Please take proper care of this Experience value. There is almost no need to earn experience points. If you earn too many points in the first half, you won't be able to avoid having them vanish in the second half !
Point #3: Use medicine, food, and tranquilizers skillfully ! You can only hold up to 14 medicines, food items, and tranquilizers. (The 15 stated in the manual is a mistake. Sorry !) It's always best to preserve the 6 or so that you hold at the start of the game. It's not good to hold to many or too few !
Point #4: Although it may seem troublesome, take careful note of the password ! While writing down the password is troublesome (sorry about that !), please record it carefully. If you keep a record of your password, even though you may encounter powerful enemies from unknown places, all of your work up to now will be rewarded. (they should have said "preserved", I think)
Point #5: What should you do when you can't proceed any further ? "I've read the manual, and tried all sorts of things, but can't get any further !" For people in this situation, please write down the situation (Who have you helped ? Which items do you have ? and so on), and send us an inquiry - the particulars are written on the back page of the manual. We'll give you special help.
Best of Luck ! From: Carpenter

On my copy of Alien Crush you struggle to fire the ball. Even then when you do you'll get no others from then on, has a very strange software bug in it. I'll have to look it out and do a video.

Supplementary (i.e. bug occurs, but not under normal operation):Dragon Slayer IIIf you run this on a system with memory at bank $49 (for example, special hardware or an emulator with this page mapped as RAM), the opening cinemas will run, but the game will stop functioning when the actual game starts (main character in bed, about to be greeted with "Ohayou"). Wait what? If by Dragon Slayer II you mean Dragon Slayer 6: The Legend of Heroes II, could you elaborate further about the bug? It's cool that it doesn't happen normally, but I feel like I want to know what triggers this bug.

It's triggered by the existence of memory that doesn't exist on a regular system. That is to say, there is basically no retail version of the system where bank $49 contains RAM.
Having said that, once emulators were created, people wondered whether it might be interesting to add some memory for homebrew purposes and so on (or perhaps memory was mapped there because it was easier than being more specific). Either way, somebody ran the game under those conditions and it didn't work correctly. elmer used Mednafen's debugger to identify the root cause, and found that the game was looking in bank $49 as though it might possibly find something there (such as developer system, etc.).
There are a wide variety of "bugs" which are in game programming which don't manifest under normal conditions, but are actually compensated for. If you wrote an emulator, and tried to figure out why 90% of games work but some don't, and look at the game code to try to figure out why.... you'll see some weird things sometimes.

That's utterly fascinating. I just totally learned something new today.
