ROM that bypassed KYODAKU becomes Invalid ROM

Open Hidetyo opened this issue 2 years ago • 9 comments

Hello,

An "Invalid ROM" error occurs in the ROM of a homebrew game that has been KYODAKU bypassed. This ROM works correctly on the emulator. This problem has been confirmed in v1.3 and automatic interim builds.

This problem occurred with the sample ROM at the URL below: https://github.com/bbbradsmith/NES-ca65-example/tree/fds

Hello. That's because file amount value is greater than actual file amount. I need to add some special mode for it, i think...

Oh... I already fixed it, lol. Are you sure that you tried the current interim build? It should be 78424a5.

Oops, I only tried Bootloder. I updated the main firmware and it works correctly.

My apologies! And thank you very much.

But when I use it with Duplifds(v1.1 and interim builds), I get an Inval ID Block error...

I know, I'll try to add some special mode to DupliFDS.

Hello from Japan.

I am interested in booting homebrew FDS files. "Lunix.fds" is known as UNIX like OS booting on the Famicom Disk System. When I am trying to bott a lunix.fds of the lng-fds project, your firmware built from a current github cloned files shows "invalid rom." Are there some advice to overcome this situation? Sincerely yours,

PS Url of lng-fds in github.com https://github.com/decrazyo/lng-fds

Some Progress. File size of linux.fds is 14 kB. So I made 65516 bytes file from the linux.fds. The file was loaded without any errors. But when I proceed to load shell program, "Error, Wrong block CRC" was displayed.
