Convert a PNG to tiles without BMP2Tiles
Post Posted: Fri Nov 20, 2020 8:41 pm
Hello! I'm new here, because I decided to learn about the programming on Master System. To continue my learning, I need to know how to convert a PNG to tiles for the Master System.

I couldn't find any examples or indications on Google. I would like a simple example in order to create my own tool that will work in Linux like I did for the Mega Drive.

Why not use BMP2Files directly? It doesn't work on Linux even with Wine.

Thanks for your help :)

Welcome to the forum!

Actually, I have used BMP2Tiles successfully on Linux with Wine; to be fair, it was called through the command line rather than through the interface, but worked okay, nevertheless.

As an alternative, you may try https://github.com/grz0zrg/bmp2sms

The older versions may work as they are straight win32, newer ones are using .net so you may need to use Mono. I may see if it ports nicely to .net 5...

@haroldoop thanks a lot :) Currently when I run BMP2Tile with Wine, the GUI does not display correctly and freeze. I tried the command line version, but it stops immediately after running:

[[email protected] bmp2tile-0.5]$ wine BMP2Tile.exe ~/Workspace/SMS/sonic.png
00f4:fixme:ntdll:NtQuerySystemInformation info_class SYSTEM_PERFORMANCE_INFORMATION


I installed the wine-mono package but it's the same. Maybe I should actually install the Mono environment as suggested by @Maxim

I will try bmp2sms :)

However, I would have liked to have understood how to create the binary file for my learning, it's exciting.

Thanks a lot for your help :)

edit: I just used bmp2sms, it's a tool that gives all the information. I now see how to create the binary file or prepare the data.

I’ve got an example using straight Python code that optimizes tiles here:

You can use png2tiles from efry.
It's a Bmp2tiles clone but only in command line. No problem to compile and use it on unix.

Old Bmp2tiles work also without problem (with wine or playonmac... On Mac, lol) . Unfortunately, same problem with recent Bmp2tiles version. Even with mono, impossible to compile/run it on my side.

PS. You can also easily manipulate png with python and PIL library.

I can run both old versions (0.4x) of BMP2Tile and new versions (0.5x, 0.6x) on wine (wine-5.0.3) on my Linux Mint. Can't remember if I had to install something more than that to make it work, probably Mono...

Hi! Yes, finally i wrote a rescomp like SGDK in C++ with Qt. This has several advantages since the data is generated for direct use in code.
