Neptune Kernels new Debug Screen - Running in VPC
Hello everyone,
This is just a small update on Neptune. I have finally gotten native Win32 compatible resources implemented in the kernel. (Well, just images anyways but still [grin]) Thanks to this, the kernel can now use bitmaps for different things…

Hello folks, this is just a small update on Neptune!
We have been working on Neptune a bit in the last few weeks. The Kernel now supports native Win32-complaint bitmap resources. Thus we can create images in any image program and create a simple resource script to compile into the kernel for it to w…

Alright... My systems boot loader consists of two separate programs. The first is a 16 bit/32 bit flat binary assembly language program (startup.sys). The second program interfaces with the first--its the bulk of the bootloader and is a 32 bit MSVC++ program. (OSLoader.exe).

MoS: New functionality
Okay... what I wanted to do is provide a method similar to DOS's int86() routine. The basic idea is that--in our 32 bit protected mode C++ program, we can call our routine (boot_services() ) to call BIOS and other real mode interrupts from protected mode.
With this new routine …

Alot of nice updates: The physical memory manager is completed and I added basic floating point support for our MSVC++ runtime library.

When reading This thread the first post seems like they were looking for a method of treating an array as a function.
In whatever case, everyone who reads that thread knows a scripting language is the best tool here. I decided "what the hey" and try it anyways :)

So I am writing a codec for ms3d model files for my engine. Pretty routine procedure. I have two files... EvehMs3d.h and EvehMs3d.cpp for the codec (along with Eveh3D's standard Link.h and Dll.cpp files for proper bindings).
Everything good so far. Then it hit... BAM! I get linker errors. Not…

I finally got around to finishing up my targa codec library (EvehTga.dll/lib). It can load 24 and 32 bpp compressed and uncompressed *.tga files. It can be used alongside the other image codecs in the same way, so using them is simple. EvehTga.dll/lib is fully integrated into…
