Re: Mode 7 demo for Genesis/MD

I wonder, can the gasega's raycast engine be used for a light-gun actions with a mechanics, specific for Virtual Cop and later generations, but a downgraded graphics?

Thank you! I look for this moment.

Re: Who's ordered an expansion ASMX architectural base? :)


The first block of quoted code correctly checks strings. The second quoted code is the problem code that is trying to pass integers to a string function.


I replaced the code from second quote with a code from first, and all the same getting a same error. Here is a test source for the each ASM ...

Re: Who's ordered an expansion ASMX architectural base? :)


Thanks. Knowing the syntax asmx uses for SH will allow us 32X/Saturn/DC folks to modify our code to work for cases where we want to use asmx instead of gas or shasm.


Now I'm trying to add the PowerPC - the heart of Sega Model 3 arcade hardware - architecture support (this arch assembly module ...

Who's ordered an expansion ASMX architectural base? :)

I hope it may some help for 32X, Saturn, and perspectively - maybe, even the Dreamcast devs.

The best place to download an ASMX sources is here.

To fully integrate a newly-downloaded asmsh.c source file in ASMX, just add the

Code: Select all

ASSEMBLER(SH);
line to arches list in asmx.c file.

Re: 68000 Arcade systems programming

Few days ago I sketched a simple slideshow demo for Metal Savior hardware, and I'd like to ask about manual conversion of colour from 8 bit per channel to 4.

The SDK I use for creation is BasiEgaXorz. For now I trying to unify the background draw subroutine, but it's look like that this ASM code plug doesn't work. Why can it be?

Everlasting Summer: Samantha (WIP)

This is a port of one of Everlasting Summer mods . For now 1st "day" is completed (taking Russian version only into account). If the game would turn out to be too big for single cartridge, I planning to split it by "volumes" which can use a common saves through a password.

Re: choice4genesis - a ChoiceScript clone for the Sega Genesis

I heard about "extreme" MegaDrive VDP modes , when VDP acquires an ability to generate an 8-, 9-, or even 12-bit images thanks to some programming tricks.
Do the tools you use for choice4genesis development allow an opportunity of such tricks? Many visual novel developers for SMD would like to use ...
