Never heard of this emulator :p

I have worried about that the data might lost forever. No matter whether it is a scam, it is part of the history. Thank you very much for preserving the data.

I guess it's not a special BIOS, but a CD with a checker application. After the application loaded, you need to swap the game CD.

My previous analysis was based on false information and completely wrong. Please don't be misled by that. There is no authentication block or magic bytes. I'm very sorry for the misleading information.

It loads the function after the Sega security check.

Hi, thank you for replying. I checked the Tamgotchi_Park.bin file and realized that my previous inference was completely wrong. My inference was based on false information, I thought the pink cartridge was a 4MB cartridge, but actually it is a 512KB cartridge (omits the even null bytes), I got...

Implemented 480P modes

Thank you for the reply. The FDD also connects to the communication port, BIOS routine sends commands via SH2.SCI to the communication port, then to the FDD. FDD then send back response data to SH2.SCI. Sanford T. Freedman did researches on the communication between FDD and SH2.SCI, based on his...

Great! Is it possible to know what protocol the printer uses to communicate with the console?

Insert printf at key steps and output messages on the screen, then you can figure out where it fails. If this doesn't work, try to simplify the program, make sure it runs on the real hardware, then add settings/functions to the simplified program, then you can figure out what settings/functions...

Nova has no such restrict currently, but I will add the restrict in future versions like other emulators. And I will add a switch like you suggested.

Simply, to avoid potential compatibility issues. There are chances to freeze the game when switching between different versions(not only different regions) of bios, e.g. if you save a game with one bios, then load the game save with another bios. There are more differences between EU and JP...

Hi, I took a look at your source code 1. D0R, D0W, D0C.., those registers are registers of SCU, have nothing to do with VDP2, make sure you referenced the right document. 2. Step by step. Write a demo that works in the normal resolution first, then extend its functionality to support other...

Thanks buddy :) I've never seen a guy who is such serious on tech details. It's great that we've made everything clear eventually. It's what we discussed for. I hope that the discussion improve and update our knowledge instead of who wins in the discussion.

This video explains nothing. Output: 1080p@60hz? First, Saturn doesn't support 1080p. Second, 60hz means 60 fields per second(30 frames per second), because VF2 runs in Hi-Res interlace mode. Please note, resolution(graphic mode) is decided by software, it has nothing to do with what monitor...
