crazyracing kartrider models (.1s)

[testing4562145]

i was able to extract the .rho archives using rholoader, but all of the model files are this, this is also used in airrider, but you need to change the .arb file extension to open them, some people ripped the models via hex editing, but it's a quite hard task as you can't find a tutorial that easily, i have provided samples for the karts and the tracks since they were more promising, the tracks also link the textures to theme/envirnoment/textures as there are none in the folders

there is also a post here 

 

karts

track models

track textures

also to note, the karts already have the textures in their designated folders, but some tracks have ones specifically related to them, where they can't be found in those common textures

characters are the same as karts, but have lots of textures and models for different expressions

"Yes~, the .1s format file divides the model structure into [Characters], [Cars], and [Maps], each with specific reading rules. Hexadecimal data records different types of tags related to the file. When a specific byte tag is read, it adopts the corresponding reading method. The file records the names of models and virtual objects, and you can find the corresponding model data areas from these sections. When you cannot view the corresponding ASCII code using UTF8, you should switch to UTF16, which will allow you to better locate the required data sections. (This is my research record on it from three years ago.)"

“是的~，.1s格式文件将模型结构分为【人物】、【汽车】、【地图】，每一个都有特定的读取规则。十六进制数据记录了与文件相关的不同类型的标签。当特定的字节标签读取时，采用相应的读取方式，该文件记录了模型和虚拟对象的名称，可以从这些部分找到对应的模型数据区，当使用UTF8无法查看对应的ASCII码时，应切换到。 UTF16，可以让你更好的定位到需要的数据段（这是我三年前的研究记录。）”

Hello, have you made any relevant teaching videos? I want to learn and analyze .1s files
