While playing a little with CC65, I quickly saw a lot of problems on PCEngine target?<\/p>\n
It’s not about the code itself, written in pure asm, since I doesn’t master the PCEngine yet but about some logic involved.<\/p>\n
<\/p>\n
Compatibility between target<\/strong><\/p>\n I understand why but trying to get the same code build the same way on some different target is a real problem.<\/p>\n We’re not talking about windows, macos, linux here…<\/p>\n We’re talking about NES, Apple2, embedded system, …<\/p>\n There are feature which are and will never be available on every target.<\/p>\n so while the ‘port CC65 lib’ to your target could be a great thing, it’s all depend on what ‘CC65 lib’ is!<\/p>\n And, for me, it’s too much.<\/p>\n <\/p>\n We don’t care about this !<\/strong><\/p>\n conio, tgi, disk, file ….it’s not what we want !<\/p>\n runtime, stdlib and some basic C functions are the bare minimum….and it’s perfect !<\/p>\n conio could be used but we don’t care about putting a char or a string on screen, we want to put tiles, with all their properties.<\/p>\n So perfect for a HelloWorld but no way for a game !<\/p>\n <\/p>\n Drivers ?<\/strong><\/p>\n Mouse and joystick are loaded like driver.<\/p>\n We’re not talking about a Personal Computer here, but a video game system, when optimization is the key.<\/p>\n So, a driver in memory, no thanks !<\/p>\n I want to read joy input every frame, from the gameloop<\/p>\n <\/p>\n <\/p>\n I pretty sure more problems will be spotted on the coming weeks but, for now, I need to take care of these ones.<\/p>\n Don’t get me wrong, CC65 is good, and the available PCEngine port (and so HuC6280’s instructions set support) is a great start.<\/p>\n But I think a dedicated PCEngine game port should be done.<\/p>\n","protected":false},"excerpt":{"rendered":" While playing a little with CC65, I quickly saw a lot of problems on PCEngine target?
