New genesis devkit

[Stef]

Hi,

I also posted this message on the Eidolon Tavern :

I've set up a small devkit for the sega genesis using GCC for win32 platform.
I compiled both GCC 3.6.0 and GCC 4.1.1 for m68k-elf target. Finally i only keep the 3.6.0 version since the 4.1.1 brings nothing interesting new (for the m68k target) and take more place. I also did some fixes on the genesis.ld file (the old one i was using was pretty... strange).

I keep the strict minimum to get your project to compile correctly and generate the rom file ! The complete archive only takes about 2.30 MB, and this is, with my libraries files

Here's the download link :

gens.consolemul.com/download/temp/GenesisDev01.zip

A small exemple of what i did with my small devkit :

gens.consolemul.com/download/temp/gencube3D.zip


And here's my blog where i deal about genesis deving :

stefda.spaces.msn.com

It containt more explanations about it but it's all french plus i don't know if you can access it

Here's a quick (and bad) translation :

contains binary files and DLL
- include --> contains the libraries headers
- lib --> contains librairies (source and obj)

In my configuration these 3 repertories are located in the
D:\apps\GenDev
Certain files have this path hardcoded, you have to
replace "D:\apps\GenDev" with your installation path if different.
The files which need to be modified are the following :
bin\makefile, bin\*.bat

To compile your program, it is very simple : execute genbuild.bat
by using the complete path (D:\apps\GenDev\genbuild.bat at home for
example) from the sources directory. If your program is correct you
should obtain a rom.bin file =) Then test it with an emulator (or
directly on the hardware if you're a lucky owner of a flash cart).
To make dev easier for me, i wrote some small basics libs. As
mentionned before the directory "include" contains the headers. I'm
too lazy to do a description of various existing functions u_u"
But the headers filename (.h) and the functions name should give you
enough to understand
I also put the sources of my rotating cube

Have fun

Wow, that's great!

And it is also good hear from you in the Genny scene.

Who knows... maybe now I have one more motivation to follow Fonzies suggestion and start coding something in C.

I hope this also motivate Devster to release the so expected new version of BasiEgaXorz.

Thanks for all.

I hope you'll have fun with that
I want to add a lot of functions to my library.
C is enough for genesis dev if you don't want ultimate performance. I'll probably add some asm functions later where it really helps, but for now all is C (except the sega.s starter file) and it'is enough to produce some nice stuff
I hope that small devkit will bring new head to the genesis dev scene (can we speak of a genesis dev scene ? )

Cool stuff. Is version 3.6.0 better than 2.95.2 for 68k stuff?

honestly ? no...
no difference in generated code.
maybe more compilation options available though... i also fixed the .ld file, now using initialised global variable shows a warning (because this is not supported on genesis platform).
