Try using the version that says [BF] with the IPS patch to fix it in my collection of fixes. If you are booting it without the menu then you'll need to fix the checksum if using the [BF] version instead of the normal version. I never tested the fix on a real cartridge so the fix may only fix one issue. I don't plan on investigating it further.

First of all, thanks for replying <3

So, I've tried it now, both with and without the menu, but the screen just stays blank when I boot the game. Is there anything I can do to try and fix it?

Another possible issue is the game writes to the Program Bank register at $2FFF which is valid, but the Smart Card doesn't like this. I would assume this is causing the crash.

So it's your lucky day I guess. I patched the ones that I saw and you can give this patch a try. Tell us if it works for you.

Once again, thanks for the attention! <3

So, I've download the patch and applied it with Lunar IPS, but it seems that nothing changed. I also tried running the game with and without the menu, but it made no difference. The only thing that's changed is that now it creates a saved data, it seems. Anything else we could try? :C

Can someone help me find the installer for this? All the links seem to be dead. Really want to be able to play Zelda! Any help much appreciated.

Regards

In case anyone else is looking for it I'll post it here. I think this is the final version I released.

Do Pocket Monsters Red and Green JPN need patching for the Smart Card too?

I think the US versions needed it so the Japanese versions very likely need a patch too. You might not, but I would expect it to need it.

Hey there, Im hoping there is someone around that could help me out...

Iv'e been trying to get two GBC games running on my ElCheapo flashcard but one (Tamagotchi) crashes to a black screen on boot, and the other (Hamtaro Ham-Hams Unite!) crashes during gameplay (I can give more detailed instructions if someone can help me out)

I checked all around the forums and online but couldn't find any evidence that someone had already patched these games.

If anyone could lend a hand, I would greatly appreciate it!

Do you mean you are using the SmartCard 64M USB or something else?

I'm using the ElCheapo SD Flash Cart made by Bennvenn, and he recommended I come here to look for patches for these games, as you guys have patched a bunch before.

If you can get information on the cartridge's registers it would help to patch those games. But I'm only familiar with the SmartCard that this thread is all about. I imagine the problem is similar in nature where the game is writing an area that on the original cartridge would do nothing but on the flash cart's hardware overwrites its special registers. Certainly though he should have added a disable for the flash cart registers to prevent this unlike the SmartCard which seems to lack that. I'm pretty sure the EverDrive GB has a proper method to protect all flash cart registers from being modified after leaving the menu system.

I can see if I can get that information from him. Yeah that's fair, I am fairly certain his flash cart works in a similar manner as the smart card usb, as patches you guys have worked on have worked on the ElCheapo as well. Yeah I'm not 100% sure, he may have tried to but ran into an issue for some reason, as far as I'm aware the card is still technically a prototype.
