First, WIN 64-bit QEMU. Only versions after qemu-2.9 support mips64. Download, install, or extract the folder. Put the patch into the installation folder to replace.

mips
mipsel
mips64el
mips64r2

Okay, it turns out that command-line ones can be universal.

qemu-system-x86_64.exe
Why can't I enter commands?
no bootable device No bootable device

qemu-system-moxie.exe This one can enter text
Enter?

qemu-system-ppc.exe This is the command-line interface
qemu-system-sparc.exe

3 different interfaces.

@drearyrain: I remember that qemu supports emulating Loongson, at least the support for 2f is available.

@drearyrain: Also, Loongnix is optimized for 3a, and it's definitely not possible to use a general-purpose MIPS for emulation.

QEMU is a free software for simulating processors written by Fabrice Bellard. It is similar to Bochs and PearPC, but it has certain features that the latter two do not have, such as high speed and cross-platform features. Through the open-source accelerator kqemu, QEMU can simulate at a speed close to that of a real computer. QEMU has two main operation modes:

User mode simulation mode, also known as user mode. QEMU can start Linux programs compiled for different CPUs. And Wine and Dosemu are its main targets.
System mode simulation mode, also known as system mode. QEMU can simulate an entire computer system, including the CPU and other peripheral devices. It makes it easy to test and debug system source code. It can also be used to virtualize several different virtual computers on one host.
The main part of QEMU is released under the LGPL, and its system mode simulation and kqemu accelerator are released under the GPL. Using kqemu can make QEMU simulate at a speed close to that of a real machine, but it is useless when the virtualized operating system is Microsoft Windows 98 or earlier.

Advantages:

Can simulate IA-32 (x86) personal computers, AMD64 personal computers, MIPS R4000, Sun's SPARC sun3 and PowerPC (PReP and Power Macintosh) architectures
Support other architectures, whether on the host or virtual system (please refer to the QEMU homepage for the complete list)
Increased simulation speed, and some programs can even run in real time
Can run Linux programs on other platforms
Can save and restore running states (such as running programs)
Can virtualize network cards
Can simulate multiple CPUs

SOSO user:
MIPS is a big-endian MIPS structure
Mipsel is a little-endian MIPS structure
The difference between them is that the byte order of the data stored in memory is reversed!
Loongson uses MIPS

How to use QEMU Manager to make an image
Step 1: Install QEMU Manager 7.0
Step 2: After starting, click the plus sign, then add the virtual machine (since there are no novices in the post, so the steps are not described).
Step 3: Click the CD-ROM button in Console, click the ellipsis, find your system ISO, double-click it, then click OK (it seems to be ok)
Step 4: Install the system
Step 5: After the installation is complete, open the QEMU Manager installation directory, find image, then find the qcow2 file with the same name as your virtual machine, and it is the image we made.

Elegant Xiaotao 250:
The command related to the block device in qemu is qemu-img, and I won't explain the various detailed parameters of this command. There are a lot of them on the Internet.
The command qemu-img create -f qcow2 filename.img is to create a disk in qcow2 format
