From 33cb13dee5a527ac445ea1b13d42723e4eb3e3b0 Mon Sep 17 00:00:00 2001 From: Franklin Wei Date: Mon, 13 Oct 2014 21:00:47 -0400 Subject: Xworld - Another World interpreter for Rockbox Co-conspirators: Franklin Wei, Benjamin Brown -------------------------------------------------------------------- This work is based on: - Fabien Sanglard's "Fabother World" based on - Piotr Padkowski's newRaw interpreter which was based on - Gregory Montoir's reverse engineering of - Eric Chahi's assembly code -------------------------------------------------------------------- Progress: * The plugin runs pretty nicely (with sound!) on most color targets * Keymaps for color LCD targets are complete * The manual entry is finished * Grayscale/monochrome support is NOT PLANNED - the game looks horrible in grayscale! :p -------------------------------------------------------------------- Notes: * The original game strings were built-in to the executable, and were copyrighted and could not be used. * This port ships with an alternate set of strings by default, but can load the "official" strings from a file at runtime. -------------------------------------------------------------------- To be done (in descending order of importance): * vertical stride compatibility <30% done> * optimization <10% done> Change-Id: I3155b0d97c2ac470cb8a2040f40d4139ddcebfa5 Reviewed-on: http://gerrit.rockbox.org/1077 Reviewed-by: Michael Giacomelli --- apps/plugins/xworld/awendian.h | 51 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 apps/plugins/xworld/awendian.h (limited to 'apps/plugins/xworld/awendian.h') diff --git a/apps/plugins/xworld/awendian.h b/apps/plugins/xworld/awendian.h new file mode 100644 index 0000000000..863b19bb47 --- /dev/null +++ b/apps/plugins/xworld/awendian.h @@ -0,0 +1,51 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2014 Franklin Wei, Benjamin Brown + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ***************************************************************************/ + +#ifndef __SYS_H__ +#define __SYS_H__ + +#include "rbendian.h" +#include "stdint.h" + + +#ifdef ROCKBOX_LITTLE_ENDIAN +#define SYS_LITTLE_ENDIAN +#else +#define SYS_BIG_ENDIAN +#endif + + +#if defined SYS_LITTLE_ENDIAN +#define READ_BE_UINT16(p) ((((const uint8_t*)p)[0] << 8) | ((const uint8_t*)p)[1]) +#define READ_BE_UINT32(p) ((((const uint8_t*)p)[0] << 24) | (((const uint8_t*)p)[1] << 16) | (((const uint8_t*)p)[2] << 8) | ((const uint8_t*)p)[3]) + +#elif defined SYS_BIG_ENDIAN + +#define READ_BE_UINT16(p) (*(const uint16_t*)p) +#define READ_BE_UINT32(p) (*(const uint32_t*)p) + +#else + +#error No endianness defined + +#endif + +#endif -- cgit v1.2.3
